Tomato Jelly

Ingredients

Directions

Make the jelly

  1. Boil the soup stock, tomatoes, onion, clove, peppercorns, salt, sugar, and catsup together for 30 minutes or until the tomatoes are soft.

  2. Soften the gelatin in ½ cup of cold water, then stir it into the tomato mixture until dissolved.

  3. Mold the mixture in a ring mold for a decorative effect.

Serve

  1. Fill the center with celery salad mixed with mayonnaise or a cooked dressing, and surround it with lettuce.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Gelatin
Sets the tomato liquid into a firm, sliceable jelly that holds its mold shape.
Tomatoes
Provide the main body, acidity and tomato flavour of the jelly.
Soup stock
Adds savoury depth and body to the tomato base.
Catsup
Adds extra tomato flavour, sweetness and tang to the base.

The step that matters

Dissolving the gelatin. Gelatin must be fully softened in cold water and dissolved into the hot mixture; if it is left undissolved or the mixture is too hot when added, it will set unevenly or lose setting power.

Swap the onion

How well each one fits the dish's main ingredients (tomato, clove, sugar, gelatin):

  1. Capsicumfits better
  2. Carrotfits better
  3. Sweet potatofits better
  4. Onionthe original

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