Wet the mixture with a little vinegar to form a thin paste, stirring until smooth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the vinegar into a smooth, pourable dressing as it cooks.
- Mustard
- Provides the sharp, pungent flavor that defines the dressing.
- Sugar
- Balances the sharpness of the vinegar and mustard with sweetness.
- Vinegar
- Supplies the liquid base and acidity that carries the other ingredients.
The step that matters
Stir the paste into the boiling vinegar. Flour lumps if it hits hot liquid unevenly. Making a smooth thin paste first and stirring constantly while it cooks lets the starch hydrate evenly and thicken the dressing without clumps.
Swap the mustard
