Cuisine: United Kingdom

Ingredients

  • 500 g cherry tomatoes small and ripe
  • 500 g preserving sugar
  • 1 stick cinnamon
  • 1 strip lemon peel

Directions

  1. Lower the tomatoes into boiling water for 25–30 seconds. Lift them out, peel, and transfer to a preserving pan.
  2. Crush the tomatoes, then add the preserving sugar, cinnamon stick, and lemon peel.
  3. Bring to a boil and simmer for 6 minutes, mashing the tomatoes as they soften.
  4. Remove the lemon peel and cinnamon. Mash until the mixture is thick.
  5. Return to a simmer for another 6 minutes.
  6. Stir well and fill warm sterilized jars, leaving about 1 cm headspace.
  7. The source then says only to “process your jars” and does not specify a process type or time. Do not infer or invent a shelf-stable process.
  8. For a conservative adaptation, cool promptly, refrigerate, and use as a refrigerated preserve. For shelf-stable tomato preserves, select a tested recipe with explicit acidification and processing instructions.
Keep this card open while you work. Ingredients and directions stay together on larger screens and stack clearly on phones.

Recipe Notes

Safety status: unverified/incomplete for shelf storage. Kilner’s page omits a defined canning method, processing time, altitude adjustment, finished acidity, and jar yield. Its claim of up to 12 months of cool, dark storage is therefore not treated here as a validated shelf-stability schedule. Safer adaptation: refrigerate this preparation, or use a tested shelf-stable tomato preserve formula from an authoritative home-canning source. Source accessed September 11, 2026.
