Orange Froth

Ingredients

Directions

Prepare

  1. Soak the gelatine in cold water for 2 hours.

  2. Peel the oranges and squeeze them.

Make the custard

  2. Heat until the sugar and gelatine dissolve.

  3. Strain the mixture through a flannel into a dish to cool.

Whip and set

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

What each ingredient does

Gelatine
Sets the liquid into a firm, wobbly structure as it cools.
Egg whites
Whipped into foam to give the set dessert its light, frothy texture.
Sugar
Sweetens the orange juice and balances its tartness.
Oranges
Supply the juice and rind that give the dish its citrus flavour and acidity.

The step that matters

Beat in the egg whites while the mixture is almost hard. If the mixture is still too liquid, the foam collapses and the froth separates; if it has set too firm, the whites will not blend in evenly. Timing the fold while it is thickened but still pourable gives a stable, airy result.

Swap the orange

How well each one fits the dish's main ingredients (sugar, egg):

  1. Vanillafits better
  2. Raisinfits better
  3. Lemonfits better
  4. Orangethe original

Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
