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

What each ingredient does

Cucumbers
Provide the main crisp, firm pickled texture.
Flour
Thickens the mustard mixture into a smooth, thick sauce.
Ground mustard
Supplies the sharp, pungent flavor that defines the pickle.
Brown sugar
Balances the sharpness of the vinegar with sweetness.
Vinegar
Acidifies the sauce, providing the tang and preserving the vegetables.

The step that matters

Stirring the flour and mustard into the hot vinegar. Pour the hot vinegar slowly while stirring constantly. Flour thickens only when it is evenly dispersed, so adding the liquid too fast creates lumps that will not smooth out.

Swap the onion

  1. Capsicumfits better
  2. Broccolifits better
