Early spring can be an invigorating time of year, with lengthening days, blooming daffodils and fruit trees (and ski season still in full force). One of the best perks of the season is the availability of luscious strawberries, and tasty artichokes and asparagus picked from nearby farms, with flavor quality and price that reflects both in-season and local transportation benefits.
Roberta Cook, UC Cooperative Extension specialist in the UC Davis Department of Agriculture and Resource Economics, in “Eye on Economics: Much more than Dollars and Cents. Cook states that, “California produces half of the nation’s fresh fruits and vegetables and consumers here are privileged to have an abundance of high quality fresh produce over extended seasons due to California’s Mediterranean climate.”
Elsewhere in the United States “local” food markets are much less developed due to climate restrictions that limit production to a brief period in the summer and early fall; and the variety of products grown is only a fraction of the over 200 crops grown in California. While “local” production represents a rapidly growing share of U.S. agricultural sales, with direct-to-consumer sales more than quadrupling in the past decade, outside of California the share is still tiny.
There are few things as disappointing as biting into a piece of fruit that looks beautiful on the outside but just doesn’t deliver that burst of flavor, or cutting into a nice-looking vegetable only to find an unsightly defect inside. When I’m prowling through a display of fresh produce, I rev up all my senses into high gear and get up-close and personal with the fruit and veggie items on my list. I get busy feeling the weight-to-size ratio, gently (not too hard, mind you, or you’ll get a bad reputation with other shoppers) pressing to feel for firmness, looking at color, form, and stem separation area, and smelling the aroma. All of these things, and more, help provide clues about the quality inside.
Other clues are often available about where and how your produce items were grown. For instance, in 2009 rules (affecting retail grocers) were adopted by the USDA mandating country of origin labeling (COOL), which required that retailers notify customers of the country of origin of all perishable agricultural commodities. Also offering insights into your produce selection is the Price Look Up sticker. Created by the Produce Marketing Association (PMA) in 1987 to create a standardized system to assist check-out clerks with looking up the produce items, it also indicates additional information such as whether it’s organic.
For instance, if your produce item’s sticker has a 4 digit code, it is “conventionally grown, but not organic.” If the code has 5 digits, and the first digit is a 9, the produce was organically grown. Usually the PLU stickers also include the country of origin in writing, but if not, this information should be displayed on the packing box or other store signage. Conventionally grown produce is recognized by scientists and regulators to be just as safe as organically grown and there is no evidence that it is worse for the environment. About 95 percent of retail fresh produce sales are conventionally grown and generally cost about 30 percent less than organics.
There are a number of resources that can help produce shoppers improve their savvy shopping skills:
From the Farm to Your Table: A Consumer’s Guide to Fresh Fruits and Vegetables, by James Thompson and Adel Kader. This 16-page booklet offers information on measuring quality; farm-based growing conditions, practices and harvesting; handling, transportation and storage; and selecting and storing good-quality produce for use at home. The table on how to select good-quality produce is especially helpful. ($7.00/copy)

There’s an old saying that “4-H isn’t just about cows and chickens.”
Well, sometimes (tongue in cheek), it’s also about chili!
As in chili cookoffs.
Every year since 2005, the Solano County 4-H Youth Development Program has sponsored a Chili Cookoff Contest as part of its Project Skills Day, where the youths share what they’ve learned in their projects. The scores of projects generally fall under the wide umbrellas of animal sciences, biological sciences, civic engagement, communication and expressive arts, community and volunteer service, environmental education and earth sciences, health, leadership and personal development, personal safety, physical sciences, plant sciences, shooting sports, and technology and engineering.
True, 4-H projects do encompass cows ‘n chickens, but topics also include other “c’s” such as computer science, citizenship, cultural arts, camping, child development and care, career exploration, cardiopulmonary resuscitation (CPR), cake decorating and crocheting.
Here’s how the Solano County 4-H Chili Cookoff works: The 4-H'ers (usually enrolled in food and nutrition projects) love chili! They form a team, create or embellish a chili recipe, and prepare the dish.
Judges sample the finished products, quiz the cooks, and score the dishes on temperature, aroma, flavor, texture, freshness and overall presentation.
In the past, the main ingredients have ranged from beef, pork, chicken, turkey and elk to strictly vegetarian. Unusual ingredients have included sweet potatoes, chile-laced mangoes, semi-sweet chocolate morsels, pineapple, coffee, beer, wine, peanut butter and bananas.
At this year’s Chili Cookoff, the winning team of Courtney Curtis, Toni DeTomasi, Halie Pringle, and Emma Couvillion of the Vaca Valley 4-H Club, Vacaville, came up with a chicken-chili recipe that wowed the judges.
“It was a great chicken chili recipe,” said judge Heidi Johnson of Dixon, one of three adults judging the event, which took place Jan. 19 in the B. Gale Wilson Elementary School, Fairfield.
Johnson, active in the Roving Clovers 4-H Club, Dixon, judged the chili cookoff with Suzanne Cline of the Rio Vista 4-H Club, and Jestine Pinon of the Tremont 4-H Club, Dixon. All praised the flavor and the texture. “It was just the right texture—not too thick and not too thin,” Pinon said.
“And the flavor was really good,” Cline said.
The winning chefs, self-described "Chili Birds," donned chicken-decorated baseball caps they’d made for the occasion.
Afterwards, they confided "This is the only chili we'll eat."
Their recipe requires eight minutes of preparation and is ready to eat in an hour and 15 minutes. So, total time from start to finish: one hour and 23 minutes.
White Bean and Chicken Chili
By the Chili Birds, Vaca Valley 4-H Club, Vacaville
2 tablespoons olive oil
1 large onion, chopped
4 garlic cloves, minced
2 pounds ground chicken
1 teaspoon salt, plus more for seasoning
2 tablespoons ground cumin
1 tablespoon dried oregano
2 teaspoons chili powder
3 tablespoons flour
Two 15-ounce cans of cannellini or other white beans, rinsed and drained
4 cups low-sodium chicken stock
Freshly ground black pepper for seasoning
1 can Ortega diced green chiles
In a large heavy-bottomed saucepan or Dutch oven, heat the oil over medium-high heat. Add the onion and cook until translucent, about 5 minutes. Add the garlic and cook for 30 seconds. Add the ground chicken, 1 teaspoon salt, cumin, fennel seeds, oregano and chili powder and the diced chiles. Cook, stirring frequently, until the chicken is cooked through, about 8 minutes. Stir the flour into the chicken mixture. Add the beans and chicken stock. Bring the mixture to a simmer, scraping up the brown bits that cling to the bottom of the pan with a wooden spoon. Simmer for 55 to 60 minutes until the liquid has reduced by about half and the chili has thickened. Simmer for another 10 minutes. Season with salt and pepper, to taste.
Other recipes showcased unusual ingredients. A team calling itself “Two and a Half Beans” from the Wolkskill 4-H Club, Dixon (Spencer and Riley Currey and Ricardo Setka), created a recipe, “Casablanca Chili,” which included sweet potatoes and chile-spiced mangoes.
The Red Hot Chili Peppers of Suisun Valley 4-H Club (Kaylee Christianson, Olivia Frenkel and Tiffany Lum) added semi-sweet chocolate chips to their recipe, “Mexican Chocolate Chili,” while a group from the Wolfskill 4-H Club (Hannah Crawford-Stewart, Madeline Pitto, Katie Polik and Kiarra Ko-Madden) offered “The King’s Chili,” using some of Elvis Presley’s favorite foods—peanut butter and bananas.
The Solano County 4-H Program is comprised of 400 youths. The clubs: Maine Prairie, Dixon Ridge, Roving Clovers, Tremont, and Wolfskill clubs, all of Dixon; Vaca Valley 4-H Club and Elmira 4-H Club, both of Vacaville; Westwind 4-H Club and Suisun Valley 4-H Club, both of Fairfield-Suisun; Sherwood Forest 4-H Club of Vallejo; and the Rio Vista 4-H Club of Rio Vista.
(The author, a longtime 4-H'er - childhood and adult - has taught such projects as swine, cooking, bonsai, photography and computer science.)
We all know that eating dark leafy greens is good for us, right? So that’s why for lunch lately I’ve been on a health kick to eat a big bowl of dark leafy greens topped with a lean protein source. I have, however, been subject to some good-natured ribbing around my office regarding my lunch selections. So I decided to research my lunch ingredients, and why I, as well as my inquisitive co-workers, already know it’s something of a power lunch, in the most nutritious of ways. First, the base of my lunch: a mix dark leafy greens (today it’s spinach, baby bok choy, and red and green chard).
The USDA describes the following general health benefits by eating your vegetables:
- Eating a diet rich in vegetables and fruits as part of an overall healthy diet may reduce risk for heart disease, including heart attack and stroke.
- Eating a diet rich in some vegetables and fruits as part of an overall healthy diet may protect against certain types of cancers.
- Diets rich in foods containing fiber, such as some vegetables and fruits, may reduce the risk of heart disease, obesity, and type 2 diabetes.
- Eating vegetables and fruits rich in potassium as part of an overall healthy diet may lower blood pressure, and may also reduce the risk of developing kidney stones and help to decrease bone loss.
- Eating foods such as vegetables that are lower in calories per cup instead of some other higher-calorie food may be useful in helping to lower calorie intake.
And specifically, dark leafy greens are nutrition-dense, with loads of vitamins (Vitamin K, C, E and B), minerals (iron, potassium, magnesium and calcium) and fiber. Additionally they contain beta-carotene, lutein and zeaxanthin, which aide in disease prevention.
Second, the toppings. I’ve left this part for the end, because those co-workers of mine thought you might not still be reading if I let you in on my super power lunch protein choice, so here it is: a can of herring.
Surprised? Yep, herring is really good (I already like herring, but I love the lemon pepper variety), and there’s no need to add dressing, just dump the whole can on your salad! Sardines, smoked oysters and tuna — all on the “Good alternative” or “Best Choice” list on the Monterey Bay Aquarium Seafood Watch — are also delicious. They’re also very convenient and relatively inexpensive, especially if you stock up when they’re on sale. Fish is a super-food of protein choices, evidenced by the USDA Dietary Guidelines for Americans 2010:
“Mean intake of seafood in the United States is approximately 3 1/2 ounces per week, and increased intake is recommended. Seafood contributes a range of nutrients, notably the omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Moderate evidence shows that consumption of about 8 ounces per week of a variety of seafood, which provide an average consumption of 250 mg per day of EPA and DHA, is associated with reduced cardiac deaths among individuals with and without pre-existing cardiovascular disease.”
A recent USDA paper says fish consumption is especially beneficial to pregnant and lactating women: “increased maternal dietary intake of long chain omega-3 fatty acids, in particular DHA from at least two servings of seafood per week during pregnancy and lactation is associated with increased DHA levels in breast milk and improved infant health outcomes, such as visual acuity and cognitive development.” (See complete February 2012 article.) And, just as I was getting ready to submit my blog, an article entitled “Brainpower Tied to Omega-3 Levels” appeared in the NY Times. How’s that for timing!
All this is not to say that chicken breast, tofu or beans are to scoff at, but do you get your USDA-recommended two servings of fish a week? What about that recommended two servings of chicken breast? Or tofu? Even beans don’t get a mention of how many times a week you should eat them. And for this I get razzed by my co-workers. Hmmph—bon appetite!
Know Your Farmer, Know Your Food is a USDA-wide effort. It is not a new department, but rather, an effort that seeks to more effectively connect existing USDA departments and work to strengthen local and regional food systems.
We know that demand for local and regional foods is strong. Per USDA statistics, the number of farmers markets has more than tripled in the past 15 years and there are now more than 7,175 around the country. The community supported agriculture (CSA) model has grown from 2 operations in 1986 to more than 4,000 today. Farm-to-school programs have experienced explosive growth, and are now found in 48 states, and total more than 2,200 (per the USDA, there were two such programs in 1996). There are “branding” efforts touting what is produced “locally” (or regionally, or statewide) in each of the 50 states.
These efforts are important: local and regional food efforts are vital to local economies, as they can often provide farmers with a higher share of the food dollar. Local jobs are supported and created in this manner, as money spent at a local business often continues to circulate within the community, creating a multiplier effect. Food dollars are good dollars.
On February 29, 2012, the USDA’s Know Your Farmer, Know Your Food initiative launched its new Know Your Farmer (KYF) Compass. The KYF Compass is a digital guide to USDA resources related to local and regional food systems. The KYF Compass organizes the USDA's work on local and regional food systems into seven thematic areas. The Compass provides tools for navigating to learn more about local and regional food systems and projects. The site enables users to secure the most up-to-date information and create interactive scenarios on a variety of topics relating to local and regional food systems, including:
- What local and regional food systems are
- Farm-to-Institution (including Farm-to-School)
- Stewardship and local food
- Local meat and poultry
- Healthy food access
- Careers in agriculture and food systems
- Case studies
- Interactive mapping tools that enable site users to locate USDA-funded local and regional food systems projects in their area (note to researchers: score!)
One of my interests is food access. The site did not fail to satisfy me in this respect. The food environment atlas tool enabled me to construct a spatial overview of the ability of specific communities to access healthy and fresh foods. In very short order, I was able to construct a rough demographic overview of how my county measured up in terms of residents’ access to grocery stores, the prevalence (and growth) of fast food restaurants, etc. This information could then be compared against other communities (or in my case, adjacent counties). This tool, along with other USDA food access tools, will prove invaluable to site users (including social science researchers). The USDA’s Economic Research Service produces some of the most cutting-edge and valuable research in this area; the site makes this information even more accessible.
The site also provides ways consumers can more directly connect with producers, a key part of building and sustaining local and regional food economies.
The Compass explicitly links food and agriculture, and shows just how interconnected the food system is with the economy, the health of communities, and the larger environment.
President Obama recently said, “Local food systems work for America: when we create opportunities for farmers and ranchers, our entire nation reaps the benefit.” The Know Your Farmer, Know Your Food initiative continues to grow, to improve and to support this vital sector of our nation’s food system.
Ever tasted a cherimoya?
“I say it tastes like heaven. The cherimoya tastes like cherimoya. It’s creamy. It’s incredible. Nothing tastes like it,” she said.
On Saturday, she helped organize a tasting of 15 varieties of cherimoya at the UC South Coast Research and Extension Center. About 120 local residents, UC Master Gardeners and members of California Rare Fruit Growers attended. Though “heaven” wasn’t an option, participants were given a scale of 1 to 5 to rate the cherimoya varieties based on exterior attractiveness, texture, flavor and overall quality.
Tammy Majcherek, who works at UC South Coast Research and Extension Center and was in charge of the tasting event, explained that the evaluations will help gardeners and homeowners better know how different varieties grow locally, before they consider planting their own.
The center has small orchards of both cherimoya and persimmon that aren’t being used for research projects, but staff members want to continue maintaining the trees and share them with the public, one way or another.
“Because of budget cuts, we've been trying to figure out ways to keep these collections going or to re-propagate some of the best," Majcherek said. "One of the things that we’re in the midst of planning is an urban horticulture extension project with a demonstration orchard, where the public can come and see the various types of trees that they could grow in this area."
Of the 100 or so cherimoya trees currently planted at the center, the best varieties would be included in the public demonstration orchard – and the results of the taste testing will eventually help staff members select which trees to plant.
The 15 varieties at the tasting were Big Sister, Booth, Chaffey, Deliciosa, Ecuador, El Bumpo, Fino de Jete, Ludica, Nata, Orton, Oxhart, Pierce, Santa Rosa, Selma and Whaley.
“I really love the Big Sister variety because the tree is kind of small and is a heavy producer,” she said. “We had a fruit from Big Sister that was the size of my whole head.”
She said that El Bumpo also produces large fruits. The varieties Fino de Jete and Nata can have excellent flavor, and this year Pierce fruits likely had the highest brix, signifying high sugar levels.
Behind the scenes, preparations for the event included harvesting the fruit more than a week ahead of time so that it would ripen.
“We picked 15 varieties the week before, and it was very stressful. Every day I was there wondering, are they going to be ripe? Are they going to be perfect for Saturday? What if they're too hard? What if they're too soft?” Barkman said. “When the cherimoya ripens, you have about two days to eat it because it will go bad really, really quickly.”
Fortunately the fruit were ripe for Saturday’s event, and extra fruit were available for participants to take home to ripen and share.
Majcherek explained this was the first time the center has organized a tasting event for the cherimoya. She was surprised that so many of the participants already knew about the fruit.
“I think they were mostly coming to the tasting just for the love of cherimoya,” she said. “I had no idea that there was such an interest.”
She plans to hold another tasting event for cherimoya next year, as well as a second tasting event for persimmons in the fall.
For more information, UC Cooperative Extension Ventura County has a page about growing cherimoya commercially and the UC Davis Postharvest Technology Center has recommendations for maintaining postharvest quality of cherimoyas too.
Information about future tastings will be posted to the UC South Coast Research and Extension Center website.
