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

What each ingredient does

Tomatoes
Provide the bulk of the pickle and release moisture that the salt draws out.
Onions
Add savory bulk and sweetness that softens during long boiling.
Coarse sea salt
Draws water out of the vegetables, firming them and concentrating their flavor before cooking.
Vinegar
Provides acidity that preserves the pickle and gives it its sharp tang.
Brown sugar
Balances the sharpness of the vinegar and adds caramel-like depth.
Mustard seed
Adds pungent flavor that mellows during simmering.

The step that matters

Stirring during the final boil. The mixture is thick with sugar and vegetables, which can scorch on the bottom of the kettle. Stirring carefully prevents burning and off-flavors, and the sugar caramelizes quickly if heat is too high.

Swap the tomato

How well each one fits the dish's main ingredients (onion, cauliflower, vinegar, sugar, mustard, allspice, clove):

  1. Horseradishfits better
