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

What each ingredient does

Isinglass
Gelatin-like setting agent that turns the liquid into a firm jelly as it cools.
Sugar
Adds sweetness and body to the jelly.
Lemon juice
Adds acidity that brightens the flavour and balances the sugar.
Spirit
Adds alcohol flavour and aroma, and softens the sweetness of the jelly.

The step that matters

Heat gently without boiling. Isinglass is a protein-based setting agent, and boiling can weaken its gelling power and cloud the jelly. Gentle heat dissolves it fully while keeping the set clear and firm.

Swap the lemon

How well each one fits the dish's main ingredients (spirit, rum, brandy, sugar):

  1. Vanillafits better
  2. Apricotfits better
  3. Applefits better
  4. Lemonthe original

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