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

What each ingredient does

Eggs
Thicken the custard when cooked and help give the ice cream a smooth, rich body.
Rich cream
Adds fat and richness, giving a smoother texture and softer bite to the frozen ice cream.
Sugar
Sweetens the base and lowers the freezing point, keeping the ice cream softer when frozen.
Milk
Forms the liquid base that the chocolate, eggs and sugar are combined into.

The step that matters

Cook the mixture in a double boiler until thickened. Gentle heat lets the egg proteins thicken the base slowly. Overheating can curdle the eggs and leave a grainy texture in the finished ice cream.

Swap the peach

The recipe marks peach as optional. How well each one fits the dish's main ingredients (chocolate, milk, egg, sugar, vanilla, cream):

  1. Coconutfits better
  2. Strawberryfits better
  3. Raspberryfits better
  4. Peachthe original

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