Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

English mustard
Provides the sharp, pungent flavor that defines the pickle and thickens the hot vinegar.
Turmeric
Gives the pickle its yellow color and a mild, earthy aroma.
Vinegar
Acidifies the mixture, preserving the vegetables and giving the pickle its tang.
Sugar
Balances the sharp acidity and mustard with sweetness.
Salad oil
Adds fat that softens the sharpness and gives the dressing a smoother mouthfeel.
Cucumbers
Soaking in salt water firms the tiny cucumbers and adds a crisp texture.

The step that matters

Stirring the mustard and turmeric into hot vinegar. Mustard powder mixed into hot liquid can clump or turn bitter if not first moistened with cold vinegar. Moistening it into a smooth paste before adding it lets it disperse evenly and thicken the dressing uniformly.
