By Marie Lefebvre · Updated October 11, 2026

Light, silky, and bursting with tropical flavor, this passion fruit marshmallow is a showstopping treat made with just three simple ingredients. The hot syrup technique creates an Italian meringue base that stays glossy and cloud-soft for days. Make it once and you'll never go back to store-bought.

🛒 Ingredients

20 servings

20
  • 3 large egg whites, room temperature
  • 2 cups (400 g) granulated sugar
  • 1 cup (240 ml) fresh passion fruit juice, strained
  • Pinch of fine salt

Directions

  1. 1

    Combine the sugar and passion fruit juice in a heavy-bottomed saucepan over medium heat, stirring only until the sugar dissolves — then stop stirring and let it cook undisturbed.

  2. 2

    Cook the syrup until it reaches the firm thread stage (about 130 °C / 265 °F). To test without a thermometer, drop a small amount into cold water — it should form a firm, pliable thread.

  3. 3

    While the syrup cooks, beat the egg whites with the salt in a clean, dry bowl until stiff, glossy peaks form.

  4. 4

    With the mixer running on medium-high, pour the hot syrup in a slow, steady stream down the inside wall of the bowl into the beaten egg whites.

  5. 5

    Keep beating for 8–10 minutes until the mixture has cooled completely and looks thick, shiny, and marshmallow-like with firm peaks.

  6. 6

    Spoon or pipe into a lightly oiled dish and rest for at least 2 hours before cutting or serving.

💡 Chef's Tip

Use freshly squeezed and well-strained passion fruit juice for the most vibrant flavor. A candy thermometer removes all guesswork from the syrup stage and guarantees consistent results every single time.
