Ingredients

Directions

Make the sauce and finish

  1. In a separate bowl, mix flour, mustard, turmeric, and enough vinegar to make a smooth paste.

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

What each ingredient does

Flour
Thickens the vinegar sauce so it becomes smooth and thick.
Mustard
Provides the sharp, pungent flavor that defines the pickle.
Vinegar
Adds acidity that preserves the vegetables and gives the pickle its tang.
Sugar
Balances the acidity of the vinegar with sweetness.
Cucumbers
Form the crisp, bulk body of the pickle.

The step that matters

Make the smooth paste before adding the vinegar. Flour lumps form if the dry ingredients are not blended with a little vinegar first. Mixing to a smooth paste lets the flour disperse evenly so the sauce thickens without clumps when boiled.

Swap the onion

How well each one fits the dish's main ingredients (cucumber, tomato, cauliflower, pepper, flour, mustard, turmeric):

  1. Lettucefits better
  2. Broccolifits better
  3. Horseradishfits better
  4. Onionthe original

Fit is the average pairing score against cucumber, tomato, cauliflower, pepper, flour, mustard, turmeric. Candidates are from the same food group and used in at least 100 recipes.
