Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts to form the fat base that the flour is cooked into.
- Flour
- Thickens the liquid as its starch swells when mixed into the hot butter and liquid.
- Cold water or milk
- Forms the liquid body of the sauce, which thickens as it heats.
The step that matters
Cooking the flour into the butter without browning. Flour must be mixed thoroughly into the melted butter and kept from browning, because a raw-tasting or browned roux changes the flavour and colour of the sauce. Adding cold liquid to the hot roux then needs stirring so lumps do not form.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
