Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat for a rich flavour and helps the flour mix smoothly.
- Flour
- Its starch thickens the hot milk into a smooth, cohesive sauce.
- Milk
- Forms the liquid base that the starch thickens into the sauce.
- Grated cheese
- Melts into the sauce, adding savoury flavour and body.
The step that matters
Adding the hot milk gradually while stirring. Starch in the flour thickens the liquid as it heats. Adding the milk slowly while stirring keeps the flour evenly dispersed, which prevents lumps and gives a smooth sauce.
