Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the sauce and carries the flavour of the dish.
- Flour
- Thickens the milk into a smooth sauce as its starch swells when boiled.
- Egg
- Adds richness and further thickens the sauce when stirred into the hot mixture.
- Butter
- Adds fat and a rich, savoury flavour to the milk.
The step that matters
Stirring the flour paste into the boiling milk. Flour lumps form if it is added to hot liquid without first being smoothed into a paste with cold or warm milk. Stirring while adding it spreads the starch evenly so the sauce thickens smoothly.
