Instructions
- Fit a stand mixer with a whisk attachment. Add the egg whites and cream of tartar and beat on medium speed until foamy.
- Add 2 tablespoons of sugar and beat until soft peaks form, set aside.
- Meanwhile, in a medium saucepan, combine water, corn syrup, and the remaining sugar.
- Cook over medium-high heat while stirring until the mixture reaches firm ball stage (*see notes) or 248°F on a candy thermometer. This step will take about 10-12 minutes.
- Once the corn syrup mixture reaches firm ball stage, turn the mixer on to medium and in a slow steady stream, pour the sugar syrup mixture into the beaten egg whites in the mixer bowl.
- Once all of the corn syrup mixture has been added, beat on high for 5 minutes.
- Add vanilla extract and beat on high for 1 minute.
- Store in a tightly sealed container.
