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

What each ingredient does

Rice
Forms the body of each snowball once boiled soft and packed into cups.
Egg yolks
Thicken the custard as they set with gentle heat, giving it richness.
Milk
Provides the liquid base of the custard and adds creaminess.
Corn starch
Thickens the custard by swelling in liquid as it heats.

The step that matters

Cooking the custard over low heat. Egg yolks can curdle or turn grainy if heated too fast. Gentle heat lets the custard thicken smoothly as the starch swells and the yolk proteins set.

Swap the lemon
