Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Provide the bulk of the filling and set firmly when cooked.
- Fat bacon
- Adds rich, savoury fat and flavour to the filling.
- Butter
- Enriches the sauce and adds flavour to the flour base.
- Flour
- Thickens the milk into a smooth sauce that binds the filling.
- Milk
- Forms the liquid base of the sauce, moistening the mixture.
The step that matters
Stirring the sauce until it boils. Flour needs to be cooked as the milk comes to a boil; otherwise the sauce stays starchy and thickens unevenly. Stirring prevents lumps and scorching on the pan bottom.
