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 color of the custard.
Eggs
Thicken the custard as they set when gently heated, giving it body.
Milk
Forms the liquid base that the eggs thicken into a smooth custard.
Sugar
Sweetens the custard and balances the bitterness of the chocolate.
Cream
Adds richness and fat, giving a softer, silkier texture.

The step that matters

Stir continuously until thickened. Egg proteins set with gentle heat, so stirring keeps the custard even and prevents it from curdling or scrambling on the bottom of the pot.

Swap the lemon

The recipe marks lemon as optional. How well each one fits the dish's main ingredients (chocolate, milk, sugar, egg, cream):

  1. Vanillafits better
  2. Coconutfits better
  3. Raspberryfits better
  4. Lemonthe original

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