Here are a few tips on how to use fennel pollen in your cooking... Fennel pollen is usually hand collected from wild fennel, which grows like mad in Italy and California (where it was planted by Italian immigrants), the two primary sources of fennel pollen. It doesn't taste like fennel seed or anise, so it truly adds a different flavor to food. It not only enhances savory dishes like meat and roasted vegetables, it is a wonderful secret ingredient to add to baking: think muffins, stone fruit pies, and breads.
My go-to recipe for roasted chicken follows Judy Rodgers's Zuni Café method, sprinkling a few teaspoons of fennel pollen across the bird as it goes into the oven.
It doesn't take much to show up in a dish: think in terms of a pinch per person. It can go on meats and in baked dishes before they cook, and it can also be dusted across a finished dish (like Batali's Tortelloni) to add a new beyond-salt-and-pepper dimension of seasoning.
I met the nice folks who run Pollen Ranch when I spoke at the Fancy Food Show last January. Based in Lemon Cove, California (don't you love that name?), they are one of only a few domestic companies harvesting and selling fennel pollen that I know of. In addition to their pure fennel pollen, they also offer a variety of mixes intended for specific foods, like Hog Heaven for Pork, and Are You Game for beef, lamb, and game.
