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

What each ingredient does

Milk
Forms the liquid base and provides the dairy fat and solids that give ice cream its body.
Egg yolks
Their proteins set when heated, thickening the custard and adding richness.
Sugar
Adds sweetness and keeps the frozen texture softer by lowering the freezing point.
Lemon juice
Adds acidity that brightens the flavour and balances the sweetness.
Vanilla extract
Contributes the primary aroma of the finished ice cream.

The step that matters

Stir over heat until thickened. Egg proteins thicken the custard as it heats, but if it overheats they scramble and curdle. Stir steadily and remove it once it coats a spoon.

Swap the lemon

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

  1. Figfits better
  2. Peachfits better
  3. Blueberryfits better
  4. Lemonthe original

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