Ingredients

  • 8 egg whites room temperature
  • 2 1/4 cups granulated sugar
  • 1/2 teaspoon cream of tartar
  • pinch of salt
  • 3 teaspoons vanilla extract

Instructions

  • 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.
