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

What each ingredient does

Cucumbers
Make up the bulk of the pulp, giving the catsup its body and fresh vegetable flavour.
White onions
Add sharp, savoury aroma that gives the catsup depth alongside the cucumber.
Vinegar
Adds acidity that sharpens the flavour and helps preserve the catsup.

The step that matters

Drain through a sieve overnight. Cucumbers hold a lot of water. Draining removes excess liquid so the catsup stays thick rather than watery in the bottle.

Swap the onion

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

  1. Capsicumfits better
  2. Radishfits better
  3. Mustardfits better
  4. Onionthe original

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