Step 1: Heat meringue over water bath

Fill a medium pot with 1 ½ inches of water and bring to a gentle simmer. In a large, heat-proof bowl that can rest over the pot without touching the water, combine egg whites, sugar, and Mayan Sea Salt. Set bowl over steaming water and stir constantly with a rubber spatula, slowly heating meringue for 9 to 10 min. until it reaches 185 degrees.

Step 2: Whip meringue

Transfer meringue mixture to the bowl of a stand mixer fitted with the whisk attachment. Whip on high for about 8 min. until meringue is glossy, stiff, and cool to the touch. With the mixer still running, add butter 1 to 2 Tbsp. at a time, letting butter incorporate fully between additions, until the mixture is thick, creamy, and soft. Add extract of choice and food coloring if using. Mix until well combined. Use immediately or transfer to an airtight container to chill for up to 2 weeks. When ready to use, bring to room temperature and whip again.
