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 body and thickening it.
Milk
Provides the liquid base and creaminess of the custard.
Sago
Starch that swells on boiling and thickens the custard.
Sugar
Adds sweetness to balance the eggs and milk.

The step that matters

Stir until it thickens slightly. Egg proteins set with gentle heat. Stirring over the boiling water bath spreads heat evenly and keeps the custard smooth, while overheating can make the eggs curdle or turn grainy.

Swap the lemon
