Floating Island

Ingredients

Directions

Make the custard

  1. Bring the mock cream to a boil.

  2. Beat the egg whites until stiff peaks form.

  3. Spoon the egg whites into the scalding cream, turning them over to set the eggs.

  4. Remove the egg whites and place them in a dish.

  5. Thicken the cream with the thin white flour batter until it reaches the consistency of thick cream.

  6. Strain the mixture, then add the beaten egg yolks, sugar, and cold milk to prevent curdling.

  7. Stir briskly and let cool.

  8. Flavor with lemon and add a pinch of salt.

Serve

  1. Serve in a large glass dish or individual glasses, topping with the reserved egg whites.

  2. Sprinkle colored sugar on top if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Whites set into soft puffs that float on the cream, while yolks enrich and thicken the custard.
Thin white flour batter
Starch thickens the hot cream to a thick, spoonable consistency as it cooks.
Mock cream
Forms the creamy base that the custard is built on and flavoured from.
Sugar
Adds sweetness and balances the flavour of the custard.

The step that matters

Adding the egg yolks with cold milk. Egg yolks can curdle or scramble when they meet hot cream. Straining first and adding the yolks with cold milk cools the mixture and helps keep it smooth.

Swap the lemon
