Beat egg whites until they begin to hold a soft peak. Gradually add artificial sweetner and continue beating until egg whites form stiff peaks. Beat in vanilla. Drop by teaspoon onto a nonstick baking sheet—or pipe the meringue from a pastry decorator. You should get 2 dozen kisses. Bake at 300°F for 25 minutes. Make a small indentation in each kiss and drop in a dab of lemon curd.
*Look for commercially prepared lemon curd in the supermarket next to the jams, jellies, and preserves. If you can't find lemon curd, you can substitute lemon pie filling.
