Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Its proteins set when heated, thickening the milk into a soft, sliceable custard.
- Milk
- Provides the liquid base and a creamy, tender texture once the egg sets.
- Sugar
- Adds sweetness to balance the mild flavour of the egg and milk.
The step that matters
Cook in water. Egg proteins set gently at moderate temperatures. Too much heat, such as a hard boil, can make the custard grainy, watery or curdled. The water bath and linen cover help soften the heat and keep the surface smooth.
