Sugar snaps are a cross between snow peas and green peas. Like a great kid, they inherited the good parts of both sides of the family. They are as sweet as young green peas and as crisp and tender as snow peas. Somewhere along the way, they also acquired a little bit of pecan flavor that makes them stand out in a stir-fry. A great source of vitamin C, sugar snaps also make a great low-fat snack.
