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, thickened by the starch-and-fat roux.
- Butter
- Melted fat that forms the roux with the flour, adding richness and smooth body.
- Flour
- Starch that thickens the liquid into a sauce when cooked with the butter and milk.
The step that matters
Adding the milk to the roux. Adding the liquid too fast or all at once can cause lumps, because flour starch clumps when it meets liquid unevenly. Stirring steadily while adding a little hot milk first helps the starch disperse, and the sauce thickens as the starch granules swell with heat.
