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

What each ingredient does

Egg yolks
Thicken the syrup as it cooks, giving the mixture a rich, custard-like body.
Heavy cream
Adds fat and whipped volume, giving the frozen dessert a light, creamy texture.
Sugar
Sweetens the base and lowers the freezing point, keeping the dessert soft rather than rock-hard.
Pistachio nuts
Add crunch and nutty flavor to the first mixture.
Strawberry puree
Adds fruit flavor, color, and moisture to the second mixture.

The step that matters

Cook the mixture until thickened. Egg yolks thicken only within a narrow temperature range. Overheating scrambles them into lumps, while undercooking leaves the base thin and unstable once frozen.

Swap the strawberry

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

  1. Coconutfits better
  2. Figfits better
  3. Cherryfits better
  4. Strawberrythe original

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