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

What each ingredient does

Mixed vegetables
Provide the bulk of the relish, with their texture softened and firmed by brining and vinegar.
Strong brine
Draws water out of the vegetables and seasons them before the vinegar is added.
Boiling vinegar
Acidifies the vegetables, preserving them and giving the relish its tangy flavour.

The step that matters

Pouring off the brine before adding the vinegar. Salty brine left in the jar would dilute the vinegar and make the relish too salty and less acidic, weakening its preservation and flavour balance.

Swap the onion

How well each one fits the dish's main ingredients (cauliflower, cucumber, radish, pepper, tomato, horse, vinegar):

  1. Mustardfits better
  2. Broccolifits better
