The flavor team

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.

Sugar and apple barely smell alike, yet cooks put them together in 16,478 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Sugar
Sweetens the dish and, when boiled, forms a clear syrup that flavours the apples.
Apples
Provide the fruit flavour and body of the sponge.
Gelatin
Sets the mixture so it holds its shape when chilled in the mold.
Lemons
Add acidity and aroma that brighten the sweetness.
Egg whites
Whipped and folded in, they add air and a light, spongy texture.

The step that matters

Folding in the egg whites. Gelatin begins to set as the mixture cools, so the mixture should be cold and only slightly thickened before the whites go in. If it is too warm, the whites deflate and the sponge turns dense; if it is too set, the whites will not blend evenly and lumps form.

Swap the apple

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

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

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