It's not just stews and casseroles that you can use your slow cooker for! This recipe for tomato ketchup is so easy, you'll wonder why you ever bought a bottle.
Ingredients
- 2 cans Tomato puree (roughly 800ml in total)
- 1 Small onion
- 1 Medium shallot
- 100ml Cider vinegar
- 75 grams Dark brown sugar
- 1/2 teaspoon Mustard powder
- 1/4 teaspoon Ground allspice
- 1/4 teaspoon Ground cinnamon
- 1/4 teaspoon Ground mace
- 1/4 teaspoon Ground ginger
- 1/4 teaspoon Ground cloves
- 1/4 teaspoon Ground red pepper flakes
- Salt and pepper
Directions
- Add the tomato puree, onion and shallot to a food processor and blitz until smooth.
- Next, add the vinegar, sugar, mustard, allspice, cinnamon, mace, ginger, cloves and pepper flakes and pulse until mixed.
- Add the contents of the food processor into your slow cooker, being sure to scrape every last bit in!
- Cook on high, with the lid on, for 2 1/2 hours.
- Cook for a further 1/2 hour with the lid off, stirring occasionally.
- Check the consistency. If you’re happy, switch your slow cooker off season to taste with salt and pepper. If you’d like your ketchup to be a bit thicker, leave it a further 15 minutes.
- Leave the slow cooker to cool before scraping your ketchup into a large sterile glass jar.
This will keep in the fridge for a while. But once opened, it’s best to eat within 2 months.
