Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the crisp, watery vegetable body of the pickle.
- Cabbage
- Adds bulk and a crisp texture that holds up after pickling.
- Vinegar
- Acidity preserves the vegetables and gives the pickle its sharp flavor.
- Sugar
- Balances the sharpness of the vinegar and adds sweetness.
- Flour
- Thickens the mustard mixture so it becomes a smooth, thick sauce.
- Dry mustard
- Contributes pungent mustard flavor to the sauce.
The step that matters
Mixing the mustard and flour into cold vinegar before adding the rest. Dry mustard and flour clump easily in hot liquid. Blending them smoothly in a little cold vinegar first keeps the sauce free of lumps when it thickens on heating.
