These delicious jumbo treats don't just taste like peppermint candies — they look like them too! To get the signature swirled look, paint stripes of gel food coloring inside your piping bag, before filling it with your meringue. When you pipe, the meringue will come out striped! You can do this with just about any color — just be sure to use gel coloring!
Preheat the oven to 250˚ F. Line 2 baking sheets with parchment paper. Beat the egg whites and salt in a large bowl with a mixer on medium-high speed until frothy. Gradually beat in the sugar and cream of tartar and beat until stiff peaks form, about 6 minutes. Add the peppermint extract and beat 2 more minutes.
Using a small pastry brush, paint four 1/4-inch-wide stripes of red gel food coloring inside a piping bag fitted with a 1/2-inch round tip. Fill with the meringue.
Pipe 2-inch spirals about 2 inches apart onto the baking sheets. Bake the meringues 1 hour, then turn off the oven and let them dry in the oven, about 2 more hours.
