Ingredients
- 3 large egg whites, at room temperature
- 3/4 cup granulated sugar
- 1/2 cup light corn syrup
- 1/4 teaspoon cream of tartar
- 1 teaspoon vanilla extract
- A pinch of salt
Instructions
- Prepare a Double Boiler: Fill a saucepan with about 1-2 inches of water and bring it to a simmer. In a heatproof bowl, combine the egg whites, sugar, corn syrup, and cream of tartar. Place the bowl over the simmering water (making sure the bottom doesn’t touch the water) to create a double boiler.
- Whisk Over Heat: Using a hand mixer or a whisk, beat the egg white mixture constantly over the simmering water. Continue whisking for about 5-7 minutes, or until the mixture becomes thick, glossy, and reaches about 160°F (70°C). The sugar should be fully dissolved, and the egg whites will have increased in volume.
- Remove from Heat: Take the bowl off the heat and add the vanilla extract and a pinch of salt. Continue beating with the hand mixer on high speed for another 3-5 minutes, or until stiff peaks form. The marshmallow fluff should hold its shape and be smooth and glossy.
- Cool and Store: Let the marshmallow fluff cool to room temperature. Once cooled, transfer it to an airtight container and store in the refrigerator for up to two weeks.
Enjoy your fluffy, homemade Marshmallow Fluff as a sweet topping for desserts, a filling for sandwiches, or a dip for your favorite treats!
