Beat egg whites and cream of tartar until soft peaks form. Beat in peppermint extract. Gradually beat in sugar until stiff, glossy peaks form. Fit a pastry bag with 1/4 inch plain tip. Using a small, clean paintbrush, brush inside of bag with 2 stripes of red food colouring opposite each other. Spoon meringue into bag. Pipe approximately 1” kisses about 1” apart onto parchment paper lined baking sheets. Bake in 200°F oven until dry, for about 1 and 1/2 hours. Turn off oven. Let stand in oven for 30 minutes. Transfer to racks to let cool. Makes about 70 kisses.
