Flageolet beans - 2 pound bag Small immature beans, flageolets become tender and retain their buff to pale green color when cooked. Serving Suggestions Flageolets are excellent served simply, with a vinaigrette, in a salad dressed with lemon, olive oil, and crème fraîche, or warm with herbs like sage or thyme and a little bacon for flavor, if desired. In France, they are typically served in soups, gratins, and especially with roast lamb. With a little advance planning, dried beans are easy to prepare, and you'll really notice the difference in flavor and especially consistency compared to canned beans.
