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

What each ingredient does

Grated unsweetened chocolate
Melts into the cream to form the rich, smooth body of the filling.
Sweet cream
Adds moisture and fat so the chocolate blends into a spreadable mixture.
Chopped walnuts
Add crunch and a toasty, bitter note that contrasts the sweet chocolate.
Chopped pecans
Add extra crunch and buttery flavour to the nut layer.

The step that matters

Stir in the nuts until thick. The chocolate and cream must be fully smooth before the nuts go in; if the chocolate is still grainy or cold, the filling will not thicken evenly and may separate or spread unevenly on the bread.

Swap the walnut

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

  1. Almondfits better
  2. Hazelnutfits about as well
  3. Peanutfits about as well
  4. Walnutthe original

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