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

What each ingredient does

Hartshorn shavings
Gelatin-rich base that sets the liquid into a firm jelly as it cools.
Beaten egg whites
Coagulate when boiled, trapping cloudy particles so the jelly strains clear.
Loaf sugar
Adds sweetness and body to the jelly.
Lemon juice
Adds acidity that brightens the flavor and balances the sugar.
White wine
Adds flavor and a little acidity to the jelly.

The step that matters

Boil quickly for a few minutes. Egg whites must be brought to a boil so they coagulate and collect impurities; boiling gently or too long can leave the jelly cloudy or cause it to break down, so the timing matters for clarity.

Swap the lemon

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

  1. Vanillafits about as well
  2. Lemonthe original
  3. Applefits less well
  4. Plumfits less well

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