Directions

Make the apple mixture

  1. Add the juice of one lemon to the strained apple juice and sugar.

  2. If the apple is tasteless, add the juice of two lemons.

  3. Soak the gelatin in cold water for 2 hours, then dissolve it in boiling water.

  4. Stir the dissolved gelatin into the apple mixture and beat thoroughly.

Set and assemble

  1. Refrigerate the mixture to thicken.

  2. Once thickened, fold in the beaten egg whites.

  3. Line a mold with lady fingers and fill it with the apple mixture.

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

What each ingredient does

Gelatin
Sets the juice mixture into a firm, sliceable structure as it cools.
Egg whites
Whipped into the mixture to add a light, airy texture.
Sugar
Sweetens the apple juice to balance the tart lemon.
Lemon juice
Adds acidity that brightens the flavor of the apple juice.
Lady fingers
Form the lining of the mold, giving the dessert a structured edge.

The step that matters

Dissolving the gelatin. Gelatin must be soaked, then fully dissolved in hot water before being stirred in. Undissolved granules leave gritty specks and uneven setting, and the mixture must be thickened but not fully set before the beaten egg whites are folded in, so they keep their volume.

Swap the apple

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

  1. Vanillafits better
  2. Orangefits better
  3. Raspberryfits better
  4. Applethe original

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