Place the egg whites and cream of tartar in the bowl of a stand mixer or a large mixing bowl. Set aside.
3 large egg whites, ¼ teaspoon cream of tartar
In a small saucepan, combine the sugar and corn syrup. Heat over medium heat, stirring occasionally, until the mixture reaches 245°F on a candy thermometer. (soft-ball stage)
¾ cup granulated sugar, ¾ cup light corn syrup, ¼ cup water
While the syrup heats, beat the egg whites and cream of tartar on medium speed until soft peaks form.
Lower the mixer speed to low. Slowly drizzle the hot syrup into the egg whites in a thin, steady stream. Avoid letting the syrup touch the whisk or bowl sides.
Increase the mixer speed to high and whip for 7–9 minutes until the mixture thickens, becomes glossy, forms stiff peaks, and the bowl cools down to the touch. Beat in the vanilla extract for 30 seconds.
1 teaspoon pure vanilla extract
Use immediately or store in an airtight container in the refrigerator for up to 2 weeks.

This recipe is ideal for larger desserts, frosting, or snacking directly.
