Recipe for Tomato Jelly

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Make the tomato jelly

  1. Cook the tomatoes with all ingredients except gelatin until well combined.

  2. Soak the gelatin in cold water for 5 minutes.

  3. Add the soaked gelatin to the hot tomato mixture and stir until dissolved.

Set and unmold

  1. Pour the mixture into a mold and refrigerate until set.

  2. To unmold, immerse the mold in warm water for a few seconds, then invert onto a serving dish.

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

What each ingredient does

Gelatine
Sets the tomato mixture into a firm jelly as it cools.
Cooked tomatoes
Provide the main body, flavour and colour of the jelly.
Tarragon vinegar
Adds acidity that brightens the tomato flavour.

The step that matters

Dissolving the gelatine in the hot mixture. Gelatine must be fully dissolved into the hot tomato mixture before setting. Undissolved granules leave gritty or weak spots, and gelatine only sets properly once it is evenly distributed and then cooled.

Flavor stand-ins for the onion

How well each one fits the dish's main ingredients (tomato, pepper, sauce, celery, clove, tarragon, vinegar):

  1. Capsicumbetter flavor fit
  2. Mustardbetter flavor fit
  3. Lettucebetter flavor fit
  4. Onionthe original

Fit is the average pairing score against tomato, pepper, sauce, celery, clove, tarragon, vinegar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
