Next time you are at the grocery store or farmers market, be on the look out for fiddleheads. Not some crazy violinist, but baby ostrich ferns, all coiled up so they resemble the scroll of a violin. They really are a delicacy and May is the time to eat them.

I must warn you though, these green plants must not be eaten raw, since they contain natural substances that can cause gastric distress if not cooked properly. So just boil them for five to seven minutes or steam them for eight, until they're just tender. You may notice that the water turns brown, which is totally normal. Be careful not to overcook them as they'll become mushy and lose their wonderful flavor, which is similar to a blend of pea pods, asparagus, and artichoke.

I was pretty impressed to find out that 3.5 ounces of fiddleheads contain only 34 calories, but an impressive 4.6 grams of protein, 370 mg of potassium, and 32 mg of calcium. So take advantage of this short season and pick some up this week. They're around $8 to $12 a pound. You can add cooked fiddleheads to pasta dishes, salads, or eat them on their own.

Fit's Tips: It's very important to know that not all ferns are edible, so it's not a great idea to go out picking fiddleheads in the woods near your house, unless you or someone you know has identified them as edible and safe. Unfortunately, fiddleheads are hard to come by outside of the northeastern US. If you can get your hands on some you are lucky!
