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

What each ingredient does

Walnuts
Provide the main nutty flavor and a fine, slightly grainy texture in the cream.
Eggs
Enrich the custard and help it thicken as it cooks.
Gelatin
Sets the mixture so it holds its shape when chilled.
Heavy cream
Adds richness and body, becoming light and airy when whipped.
Egg whites
Whipped foam adds lightness and a airy, delicate texture.
Lemon juice
Adds acidity that brightens the sweetness of the custard.

The step that matters

Folding in the whipped egg whites. Whipped egg whites and cream trap air that gives the cream its lightness. Stirring hard or too long deflates the foam, leaving a dense result. Fold gently with a spatula until just combined.

Swap the walnut

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

  1. Almondfits better
  2. Pistachiofits better
  3. Chestnutfits about as well
  4. Walnutthe original

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