2 large egg whites (room temperature)
-
1 cup granulated sugar

¼ cup water

¼ teaspoon cream of tartar
-
1 teaspoon vanilla extract
-
Pinch of salt
-
2 tablespoons light corn syrup (optional but helps texture)
Equipment

Instructions
1. Make Sugar Syrup
-
In a saucepan combine:
-
sugar
-
water
-
corn syrup

-
Heat over medium heat without stirring until it reaches 240°F / 115°C (soft-ball stage).
2. Whip Egg Whites
-
While the syrup heats, place egg whites in a mixing bowl.
-
Add cream of tartar and salt.
-
Beat on medium-high speed until soft peaks form.
3. Combine
-
When the syrup reaches 240°F, remove from heat.
-
Slowly pour the hot syrup in a thin stream into the egg whites while mixing on low.

Increase speed to high and beat for 5–7 minutes.
The mixture will become thick, glossy, and fluffy.
4. Finish
-
Add vanilla extract.
-
Beat another 30 seconds until fully combined.
Your marshmallow fluff is ready.
