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

What each ingredient does

Chocolate
Provides the main flavor and dark color of the sauce.
Sugar
Adds sweetness and body to the chocolate sauce.
Flour
Thickens the sauce slightly when mixed with water and stirred in.
Butter
Adds richness and a smooth, glossy texture.

The step that matters

Thickening with flour. Flour must be mixed smooth with a little cold water before adding, otherwise it clumps. Stirring it into hot sauce helps it thicken evenly.

Swap the walnut

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

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