Orange Charlotte

Ingredients

Directions

Make the orange jelly

  1. Soak the gelatine in cold water until soft.

  2. Pour the boiling water over the gelatine, then add the sugar and lemon juice.

  3. Strain the mixture and add the orange juice, pulp, and a little grated rind.

  4. Cool the mixture in a pan of ice water.

Set and serve

  1. Beat the egg whites until stiff.

  2. When the orange jelly begins to harden, fold in the beaten egg whites until well combined.

  3. Pour the mixture into a mould lined with lady-fingers or orange sections.

  4. Optionally, top with whipped cream after removing from the mould.

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

What each ingredient does

Gelatine
Sets the juice into a firm, sliceable jelly that holds its shape when unmoulded.
Egg whites
Whipped to stiff foam that lightens the jelly and gives it an airy, fluffy texture.
Sugar
Sweetens the jelly and balances the sharp citrus flavour.
Orange juice and pulp
Provides the main orange flavour and body of the jelly.

The step that matters

Fold the egg whites in as the jelly begins to set. If the jelly is still liquid, the whites deflate and the mixture separates; if it is too firm, the whites won't blend evenly and lumps form. Chilling to a thick, syrupy stage keeps the foam stable while it is folded in.

Swap the orange

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

  1. Orangethe original
  2. Vanillafits about as well
  3. Limefits less well
  4. Raisinfits less well

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