🛒 Ingredients

2 servings

2
  • 250 ml (1 cup) water
  • 2 tablespoons granulated sugar
  • 1 tablespoon cornstarch
  • 1 packet flavored or colored gelatin powder (color of your choice)

Directions

  1. 1

    In a small saucepan, whisk together the water, sugar, and cornstarch until fully combined and lump-free.

  2. 2

    Place over low heat and stir constantly with a whisk or spatula to prevent lumps from forming and the mixture from sticking.

  3. 3

    As soon as the mixture starts to thicken and turn clear, stir in the colored gelatin powder and mix well.

  4. 4

    Remove from heat immediately, let cool for 2–3 minutes, then brush onto your cake or tart using a pastry brush.

💡 Chef's Tip

Apply the glaze while still warm for the smoothest, shiniest coat. For a mirror-glaze effect, allow it to cool slightly more before brushing on. Keeps refrigerated for up to 3 days.
