Total Time20 mins
- 8 egg whites room temperature
- 2 1/4 cups granulated sugar
- 1/2 teaspoon cream of tartar
- pinch of salt
- 3 teaspoons vanilla extract
Pour about 1/2 cup of water into a medium-sized saucepan and bring to a simmer.
Add egg whites, sugar, cream of tartar, and salt to the bowl of an electric mixer. Whisk with hand-held whisk until the ingredients begin to become foamy.
Place the bowl over the saucepan of simmering water and continue to whisk until the sugar is completely dissolved, about 5 minutes.
Remove the bowl from the saucepan and transfer to a stand mixer with the whisk attachment attached. Turn mixer to medium setting and whip for about 1 minute. Increase the speed to high and whip until stiff peaks are formed, about 5-7 minutes. Reduce speed and incorporate vanilla.
