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

What each ingredient does

Cream
Adds richness and body, giving the frozen ice cream a smooth, creamy texture.
Eggs
Thicken the base when heated and add structure and richness to the custard.
Syrup
Adds sweetness and helps keep the frozen ice cream soft rather than rock hard.
Barcelona nuts
Roasting browns the nuts and gives the ice cream its deep, toasty, burnt flavour.

The step that matters

Boiling the custard until it thickens. Egg proteins set as the mixture heats, which thickens it. If it gets too hot or boils too long, the eggs can curdle and turn grainy, so stop as soon as it thickens.

Swap the nuts

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

  1. Pistachiofits better
  2. Almondfits better
  3. Chestnutfits about as well
  4. Nutsthe original

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