Peppermint Meringue Cookies

"Whenever I make ice cream from scratch, we usually have lots of leftover egg whites to use up. Meringues (or as my nephew calls them, “little pavlovas”) are little cookies made with basically just egg whites and sugar, with a little vinegar and salt added to help the mixture hold its structure when whipped.
