Sugar and milk barely smell alike, yet cooks put them together in 77,875 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 as they cook and add richness and a smooth texture.
Pistachio nuts
Provide the main flavour and colour, with oil that adds richness to the base.
Milk
Forms the liquid base that the custard sets from, carrying the flavour and creaminess.
Sugar
Sweetens the base and helps keep the finished ice cream soft rather than rock-hard.

The step that matters

Cook the custard in a bain-marie. Egg yolks thicken at gentle heat, around 70 to 85°C. Heating them too fast can scramble them into lumps, so gentle indirect heat and steady stirring keep the custard smooth.

Swap the nuts

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

  1. Almondfits better
  2. Walnutfits better
  3. Chestnutfits better
  4. Nutsthe original

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