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

What each ingredient does

Egg yolks
Thicken the custard and add richness through emulsified fat and proteins.
Heavy cream
Adds fat that keeps the frozen texture smooth and creamy rather than icy.
Sugar syrup
Sweetens the base and lowers the freezing point, keeping the ice cream softer.
Orange zest
Adds aromatic citrus oils for flavour.

The step that matters

Beat the custard without boiling it. Egg yolks thicken as they heat, but above about 82°C they scramble and curdle, leaving a grainy custard. Keeping the mixture below boiling keeps it smooth.

Swap the orange

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

  1. Vanillafits better
  2. Raisinfits better
  3. Strawberryfits better
  4. Orangethe original

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