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

What each ingredient does

Isinglass
Sets the liquid into a firm, wobbly gel as it cools.
Orange juice
Provides the main flavor and acidity of the jelly.
Lemon juice
Adds sharp acidity that balances the sweetness.
Loaf sugar
Adds sweetness and lifts the citrus oils from the rind.

The step that matters

Boil for a few minutes, then strain through flannel. Boiling fully dissolves the isinglass so it can set evenly on cooling. Straining through flannel removes particles and cloudiness, giving a clear jelly.

Swap the saffron

The recipe marks saffron as optional. How well each one fits the dish's main ingredients (orange, lemon, sugar):

  1. Cinnamonfits better
  2. Gingerfits about as well
  3. Saffronthe original
  4. Peppermintfits about as well

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