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

What each ingredient does

Peanut butter
Provides fat and rich peanut flavor that defines the sauce.
Sugar
Adds sweetness and forms the caramel-like body of the sauce when heated.
Cream
Adds fat and moisture for a smooth, pourable texture.

The step that matters

Stir until it begins to become grainy. The sugar mixture is taken off the heat and stirred as it starts to turn grainy, which is sugar beginning to crystallize. Because this texture changes quickly, timing the removal from the heat matters.

Swap the peanut

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

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

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