How to Preserve Chillies & Make Chilli Jam

Written by Sarah Talbot


When hot weather leads to a bumper chilli crop you might find you have too many chillies.  Having eaten them every day since August and made Chilli Sauce, Chilli flakes, Chilli truffles and 3 types of Chilli Oil here is a new recipe to help use the glut.

Chillies and tomatoes are great to grow but difficult to keep for long. So if you would like to remember your summer fruits from the garden, chilli jam is an excellent and delicious memory. Great in a cheese sandwich, fried up with chicken or you could put a couple of teaspoons in your soup to spice it up. Jump to the Recipe or read on for our chilli facts. 

Fun Chilli Facts

🌶️ Think you know everything about chillies? Check out these incredible facts that'll spice up your knowledge:

  • 🔥 Jalapeño, Habanero, and Carolina Reaper are just the tip of the iceberg when it comes to varieties – there are over 400 types in existence!

  • 💚 Chillies can be green, yellow, orange, red, or even purple!

  • 🌶️ One chilli plant will often give you 100 chilies or more (you really like chillies- right?!)

  • 😋 Capsaicin, responsible for the heat, also triggers the production of endorphins (happy hormones)! Guess that's why we love a chilli!

  • 🔥 Chili pepper seeds are not the spiciest part of the pepper. The “hottest” part of the pepper is actually the part of the pepper where the seeds are located next to the pepper's white membrane.

Chilli Jam Recipe


8 red peppers.

10 red chillies.

1 finger-sized piece of fresh root ginger, peeled and roughly chopped

8 cloves of garlic

14oz (400g) of fresh tomatoes chopped – or a 400g tin of cherry tomatoes

1lbs 8oz (750g) Preserving sugar this also helps not to make the jam too runny

7 floz (200ml) red wine vinegar

Preparation: 20 minutes Cooking time: 60 – 90 minutes

How to make the jam:

1. Cut up your peppers and chillies keeping the chilli seeds but not the pepper ones. Put them into the food processor along with the garlic and ginger.

2. Scrape into a heavy-bottomed pan with the tomatoes, sugar and vinegar, then bring everything to the boil.

3. Turn the heat down to a simmer and cook for about 50 minutes, stirring occasionally – skim off any scum that comes to the surface.

4. Once the jam becomes sticky, continue cooking for 10-15 minutes more, stirring frequently so that it doesn’t burn on the bottom of the pan. It should now look like thick, bubbling lava.

5. Cool slightly, transfer into sterilised jars, cover with lids straight away to create a vacuum, then leave to cool completely.

6. Keeps for 3 – 12 months in a cool, dark cupboard - once you have opened it keep it in the fridge.
