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

What each ingredient does

Sugar
Provides sweetness and, as it dissolves and cooks, helps set the filling's body.
Cream or milk
Adds moisture and richness, giving the filling a smooth, creamy texture.
Unsweetened chocolate
Supplies the chocolate flavor and deep color, and its fat helps give the filling body.
Butter
Adds fat for a smoother, glossier texture and a richer mouthfeel.

The step that matters

Cook until thickened, then beat. Sugar and milk solids thicken as the mixture cooks and cools, so stopping too early leaves the filling runny. Beating while it cools adds air and makes it spreadable.

Swap the walnut

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

  1. Almondfits better
  2. Hazelnutfits better
  3. Chestnutfits better
  4. Walnutthe original

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