Make the aspic

  1. Combine tomatoes, chopped onion, allspice, peppercorns, salt, and bay leaf in a saucepan.

  2. Bring to a boil and cook until the onion is soft.

  3. Strain the mixture through a wire sieve, using the back of a spoon to push as much through as possible.

  4. Dissolve the gelatin in a small amount of warm water. Add the dissolved gelatin to the strained mixture.

Set and serve

  2. Garnish with shredded lettuce. Serve with mayonnaise.

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

What each ingredient does

Gelatine
Sets the strained tomato liquid into a firm, sliceable jelly.
Tomatoes
Provide the main body, acidity and flavour of the aspic.
Onion
Adds savoury sweetness and aroma to the tomato base as it softens.

The step that matters

Dissolve the gelatin in a small amount of warm water. Gelatine must be fully dissolved before it is added, or it will form lumps and set unevenly. Too much heat can weaken its setting power, so keep the water warm rather than boiling.

Swap the allspice

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

  1. Garlicfits better
  2. Capersfits better
  3. Cuminfits better
  4. Allspicethe original

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