Foraged from the ostrich fern, fiddleheads are the plant's young shoots that look like tiny scrolls popping out of the dirt. Only available for a short window of time during the spring, they are a delicious delicacy with many devoted fans who can hardly wait for fiddlehead season. Fiddleheads are foraged from the wild in certain parts of the U.S. and Canada, where they're also most often consumed. Some foragers sell them to markets, making them available to more people. Best when simply prepared by sautéing or steaming right after harvest, fiddleheads offer a charming taste of spring for simple dishes.
