This recipe shows you how to make meringue cookies by warming egg whites and granulated sugar in a double boiler, whipping them until stiff peaks form, and flavoring them with strawberry powder and lemon zest. By coloring the inside of a piping bag with food coloring, you can create adorable two-tone teardrop-shaped meringues. Baking them slowly at a low temperature and letting them cool in the oven results in a crisp texture. These visually appealing cookies are perfect as gifts or for enjoying at home.
