Cherub Puffs (Christmas!) (From the kitchen of Gramma Taylor)

Cover baking sheet with foil. Add vanilla and vinegar (or cream of tartar) to egg whites and beat until soft peaks form. Add sugar and beat until very stiff. Fold in chocolate chips. Drop by teaspoon-full onto aluminum foil-lined baking sheet. Bake in 300° degree oven for 25 to 30 minutes. Remove from oven, cool, and peel from foil.

Makes about 4 dozen.
