You know spring has sprung when fava beans come back to markets and menus. Colorado chef Jennifer Jasinski, whose Denver restaurants include Rioja and Bistro Vendôme, says she's uniquely positioned to get the most out of fava season: In early spring, Colorado gets favas from neighboring states, while the local fava growing season stretches until June.

"It's fantastic. We get almost five whole months of fresh favas," Jasinski says. "I love their sweet, delicate flavor and creaminess. When the springtime comes, I just want to see their young, bright-green color."

Because the beans have such delicate flavor and texture, Jasinski says it's best to feature them simply, without a lot of other ingredients that might mask their subtleties. Dishes like pasta tosses or even just scrambled eggs let the beans come through in all their verdant glory.

Jasinski's crostini is another great example of a simple fava dish. Paired with tangy goat cheese and meaty mushrooms on crunchy toasted bread, the favas get the seasonal star treatment. "I just wanted to make a simple little appetizer, a nice party snack, where the favas wouldn't be overwhelmed," she says. She succeeds deliciously. Try Jasinski's original version this month at Rioja in Denver.
