Ingredients:
- 4 large egg whites, room temperature (about 120–132 g total egg white)
- 1 cup (200 g) superfine or granulated sugar (superfine preferred)
- 1/4 teaspoon (1 g) cream of tartar (or 1/2 teaspoon white vinegar or 1/2 teaspoon lemon juice)
- Pinch fine sea salt (about 1/8 teaspoon)
- 1/2 teaspoon (2.5 ml) peppermint extract
- 1/4 teaspoon (1.25 ml) vanilla extract (optional)
- Red gel food coloring, a few drops (optional, for swirls)
- 1/3 cup (50 g) crushed peppermint candy or candy cane, divided (reserve some fine dust and some coarser pieces for decoration)
Instructions:
- Preheat oven to 200°F (95°C) and place racks in the middle and lower positions; line baking sheets with parchment or silicone mats and prepare a piping bag and tip.
- Crush candy canes in a zip-top bag with a rolling pin; reserve 1–2 tablespoons of very fine dust for sprinkling and keep the rest coarser for decoration.
- Ensure mixing bowl and whisk are impeccably clean and dry; place room-temperature egg whites in the bowl and add cream of tartar and salt.
- Whip egg whites on medium until soft peaks form, then with mixer running add sugar gradually (about 1 tablespoon at a time or in a slow steady stream) until fully incorporated and mixture is glossy.
- Continue whipping to stiff, glossy peaks; test by lifting the whisk — peaks should stand straight without drooping and sugar should feel dissolved between fingers.
- Gently fold in peppermint extract and vanilla if using; for swirls, add a few drops of red gel into the piping bag before adding the meringue to create stripes.
- Fill piping bag and pipe small 1-inch (2.5 cm) kisses spaced about 1 inch apart (or pipe larger 1.5–2 inch rounds); sprinkle with crushed candy cane pieces while meringues are still tacky.
- Bake at 200°F (95°C) for 1 hour 30 minutes until meringues are dry and lift cleanly from the parchment; turn off oven, prop the door open and let meringues cool and dry in the oven for 1 hour to prevent cracking.
- Remove cooled meringues and store in an airtight container at room temperature in a dry place for up to 1–2 weeks; do not refrigerate.
