The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.

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 when gently heated and add richness and a smooth texture.
Cream
Adds fat for a rich, smooth mouthfeel and softer frozen texture.
Sugar
Adds sweetness and keeps the frozen ice cream from freezing too hard.
Chestnut flour
Its starch thickens the base and gives the ice cream its nutty flavour.
Whipped cream
Incorporates air into the frozen mixture, making it lighter and less dense.

The step that matters

Stir over heat until thick, then strain. Egg yolks can scramble if the custard gets too hot. Stir gently over moderate heat, and strain to remove any lumps before freezing.

Swap the chestnut

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

  1. Almondfits about as well
  2. Chestnutthe original
  3. Hazelnutfits about as well
  4. Macadamia nutfits about as well

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