🛒 Ingredients

4 servings

4
  • 1 cup (200 g) granulated sugar
  • ½ cup (120 ml) water
  • 3 large egg whites, room temperature
  • 1 teaspoon pure vanilla extract
  • Pinch of salt

Directions

  1. 1

    Combine sugar and water in a small saucepan over high heat. Cook without stirring until the syrup reaches the soft-thread stage (110–112 °C / 230–234 °F).

  2. 2

    Meanwhile, beat the egg whites with a pinch of salt until they form soft, glossy peaks.

  3. 3

    With the mixer running on medium speed, slowly pour the hot syrup in a thin, steady stream into the egg whites.

  4. 4

    Add the vanilla extract and continue beating until the mixture cools completely, thickens, and becomes fluffy and firm.

  5. 5

    Use immediately to frost cakes or pastries, or transfer to a lightly greased dish and refrigerate for 30 minutes until set.

💡 Chef's Tip

For a firmer marshmallow, cook the syrup to 118 °C (245 °F / firm-ball stage). Try a drop of almond or peppermint extract for a fun flavor twist.
