Instructions

1. Prepare Egg Whites

• Attach the whisk to a stand mixer. Add the egg whites and cream of tartar, and beat on medium speed until foamy.
• Gradually add 2 tablespoons of sugar to the egg whites and continue beating until soft peaks form. Set aside.

1. Cook the Sugar Mixture

• In a medium saucepan, combine water, corn syrup, and the remaining sugar.
• Cook over medium-high heat, stirring occasionally, until the mixture reaches the firm ball stage (248°F on a candy thermometer). This should take about 10-12 minutes.

1. Combine the Mixtures

• Once the syrup reaches 248°F, turn the stand mixer to medium. In a slow, steady stream, pour the hot syrup into the egg whites, taking care not to pour directly onto the whisk.

1. Whip to Fluff

• After all the syrup has been added, increase the mixer speed to high and beat for 5 minutes.
• Add the vanilla extract and beat for another minute until smooth and fluffy.

1. Store and Enjoy

• Transfer to a tightly sealed container and refrigerate. Use as needed for an airy, sweet addition to your recipes.

Tips for Perfect Marshmallow Fluff

• Temperature Check: Use a candy thermometer for accuracy—this is key to achieving the right marshmallow texture.
• Slow Pour: When adding the hot syrup, pour slowly to ensure even incorporation and prevent cooking the egg whites.
• Storage: Homemade marshmallow fluff can be stored in the refrigerator for up to two weeks in an airtight container.

This marshmallow fluff is a lovely, nostalgic addition to recipes or as a topping—delightfully sweet, with just the right hint of vanilla.
