Method

1
For the tomato ketchup, place a large pan over a medium heat and add a tbsp of oil

Once the oil is hot, add the onion and garlic and cook for 2 minutes, or until the onion is soft and translucent
  • 1 red onion, peeled and chopped
  • 2 garlic cloves, peeled and sliced
3
Wrap the peppercorns up in muslin cloth, tie up firmly with cooking string
  • 10 black peppercorns

  • 2 tsp thyme, chopped
  • 1/2 cinnamon stick
  • 50g of caster sugar
  • 2 bay leaves

Cook for 15 minutes, or until the tomatoes have broken down and their liquid has been released

Continue to cook until the tomato liquid has reduced and the tomatoes start to catch. Then, add the vinegar, turn up the heat and boil for 5 minutes
  • 150ml of red wine vinegar
7
Transfer the contents of the pan to a blender, removing the cinnamon stick, bay leaves and peppercorn bundle
8
Blend the tomatoes until smooth and then pass through a sieve

16
Lay the patties out on a tray and refrigerate until required. When you are ready to cook, preheat the oven to 200°C/gas mark 6
