Meringue cookies are light, crisp desserts made primarily from whipped egg whites and sugar. Their airy structure forms when egg whites are beaten until stiff peaks develop, trapping air that expands during baking. The cookies are baked at a low temperature to dry them rather than brown them.The result is a delicate cookie with a crunchy exterior and a melt-in-the-mouth texture. Meringue cookies can be flavored with vanilla, cocoa powder, fruit extracts, or even folded with chocolate chips or nuts.They are perfect for elegant dessert platters, gift boxes, or as a light sweet snack. Because they contain no flour, they are naturally gluten-free. Their long shelf life also makes them an ideal make-ahead treat for holidays and parties.
