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

What each ingredient does

Eggs
Set when heated, giving the custard its firm, sliceable structure.
Milk
Provides the liquid base and moisture that keeps the custard tender.
Sugar
Adds sweetness and balances the savory taste of the eggs and milk.

The step that matters

Watch the custard as it sets in the water bath. Egg proteins set with gentle heat, and too much heat makes the custard curdle, weep or turn rubbery. Keeping the water below a bubbling boil and removing the cups once set prevents overcooking.
