The Ostrich fern, commonly found in northern Maine, is known for its unique edible feature when young. During this stage, the fern’s frond is tightly curled, and is often consumed fresh by locals. It can also be found canned in other regions. When cooked, the fern’s flavor profile is often described as a mixture of asparagus and mushroom, and is typically prepared in a similar fashion to broccoli. Despite its limited availability outside of its native region, the Ostrich fern remains a beloved culinary delicacy for those who are fortunate enough to enjoy it.
The edible delicacy you are referring to is called “fiddleheads”. They are the young, curled fronds of several species of ferns that grow in Canada and the United States. Fiddleheads are considered a seasonal delicacy, and are only good to eat before they unfurl. They are typically cooked briefly by boiling in water and then served with butter or hollandaise sauce. Fiddleheads have a unique flavor and texture, and are often enjoyed by those who appreciate foraged foods.
