Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the milk as it cooks and gives the filling its set structure.
- Flour
- Stabilises the custard so it thickens smoothly without curdling.
- Milk
- Forms the liquid base that the egg and flour thicken into a filling.
- Sugar
- Adds sweetness and softens the set, giving a smoother texture.
The step that matters
Cook over medium heat while stirring constantly. The egg proteins set as the mixture heats. Stirring keeps heat even and prevents the egg from curdling or scorching on the bottom of the pan, which would leave lumps.
