Orange Charlotte

Ingredients

Directions

Make the orange jelly

  1. Soak the gelatine in cold water until soft.

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

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

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

Whip and fold

  1. Beat the egg whites until stiff.

  2. When the orange jelly begins to harden, beat it until light, then fold in the beaten egg whites until stiff enough to drop.

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

What each ingredient does

Gelatine
Sets the orange mixture into a firm, sliceable jelly.
Egg whites
Whip into foam that makes the charlotte light and airy.
Sugar
Sweetens the jelly and balances the sharpness of the citrus.
Orange juice and pulp
Provides the main orange flavour and liquid for the jelly.
Lemon juice
Adds acidity that brightens the orange flavour.

The step that matters

Cool the jelly until it just begins to harden before folding in the egg whites. If the jelly is still liquid, the beaten whites collapse and deflate. If it has set firm, it will not blend smoothly and the foam loses its lightness. Timing at the partly set stage keeps the air in the whites.

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.
