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

What each ingredient does

Cucumbers
Provide the crisp, bulky body of the pickle after soaking in salt water.
Cauliflower
Adds firm texture and absorbs the vinegar and mustard flavour.
Ground mustard
Supplies the pungent, sharp flavour that defines the pickle.
Flour
Thickens the vinegar mixture into a smooth, cohesive sauce.
Vinegar
Provides the acidity that preserves and sharpens the vegetables.
Sugar
Balances the sharp acidity and mustard with sweetness.

The step that matters

Smoothing the flour and mustard with cold vinegar. Adding flour to hot liquid without first blending it into cold vinegar causes lumps, because starch clumps before it disperses. A smooth paste disperses evenly when poured into boiling vinegar, which then thickens it.
