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

What each ingredient does

Gelatine
Sets the tomato liquid into a firm, wobbly aspic once chilled.
Tomatoes
Provide the main body, flavour and colour of the aspic.
Lemon juice
Adds acidity that brightens the tomato flavour.

The step that matters

Dissolving the gelatine. Gelatine must be fully dissolved into the hot tomato mixture, not left in lumps. Boiling the mixture is fine, but undissolved gelatine will leave gritty spots and weaken the set once chilled.

Swap the onion

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

  1. Capsicumfits better
  2. Okrafits better
  3. Spinachfits better
  4. Onionthe original

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