Orange Charlotte

Ingredients

Directions

Make the orange jelly

  1. Soak the gelatin in cold water until soft.

  2. Pour the boiling water over the gelatin and 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.

Whip and set

  1. Beat the egg whites until stiff.

  2. When the orange jelly begins to harden, beat it until light.

  3. Fold in the beaten egg whites until stiff enough to drop.

  4. Pour the mixture into a mold.

  5. Optionally, use 1 pint of whipped cream instead of egg whites, or pile it on top after removing the charlotte from the mold.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Gelatin
Sets the liquid into a soft, sliceable jelly that holds its shape.
Egg whites
Whipped into foam that lightens the mixture and gives it an airy texture.
Sugar
Sweetens the jelly and balances the tartness of the citrus juices.
Orange juice and pulp
Provides the main orange flavor and some body to the jelly.
Lemon juice
Adds acidity that brightens the orange flavor.

The step that matters

Beat the jelly only when it begins to harden. If the gelatin mixture is still liquid, beating will not add air and it will not hold foam; if it is fully set, it cannot be whipped smooth. Cooling to a partly set state lets the whites fold in evenly and stay light.

Swap the orange

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

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

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