What each ingredient does
- Flour
- Thickens the sauce as its starch swells and sets when heated in the liquid.
- Vinegar
- Adds sharp acidity that gives the sauce its tangy flavor.
- Boiling water
- Forms the liquid base that the flour thickens into a sauce.
The step that matters
Cook for the full 10 minutes after the mixture boils. Flour starch only thickens fully once it is heated in the liquid and cooked through. Stopping early can leave the sauce thin and give it a raw, pasty taste.
