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

What each ingredient does

Egg yolks
Thicken the milk into a custard and add richness.
Gelatine
Sets the custard into a firm, sliceable jelly as it cools.
Milk
Forms the base of the custard and provides moisture.
Sugar
Adds sweetness to the custard.

The step that matters

Stir the custard over low heat without boiling. Egg yolks thicken at gentle heat but curdle and turn grainy if they boil, so the custard must stay below a simmer.

Swap the lemon

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

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