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

What each ingredient does

Sugar
Adds sweetness and helps set the filling as it cooks.
Chocolate
Provides the chocolate flavor and deep color.
Milk
Adds moisture and creaminess to the filling.
Butter
Adds richness and a smoother, glossier texture.

The step that matters

Boiling until it nearly threads. Boiling concentrates the sugar and sets the filling's texture. Stop too early and it stays runny; go too far and it turns grainy or hard as it cools.

Swap the walnut

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

  1. Almondfits better
  2. Cocoafits better
  3. Pecansfits better
  4. Walnutthe original

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