Shallots: peel the shallots, slice in halves and then add them to the food processor. Give them a quick blitz (2-3 seconds) to roughly chop.
Fry: add the diced bacon, blitzed shallots and garlic to a large sauce pan. Turn the heat to high and cook for 8-10 minutes. Use a wooden spoon during this time to move the ingredients about, ensuring that the ingredients are mixed together well and cooking consistently.
Tomato and chilli: next use a sharp knife to remove the stems from the chilli and discard. Then use the same knife to cut the top off each tomato and the remaining tomato in halves. Add the tomatoes and chilli to the food processor and blitz for 5 to 10 seconds.
Remaining ingredients: next add the brown sugar, red wine vinegar, lemon juice, Worcestershire sauce and salt to the blitzed tomatoes and chilli. Then blitz these to combine.
Combine: remove the lid from the food processor and transfer the tomato mixture into the sauce pan with the cooked bacon mixture.
Cook: place the saucepan onto the stovetop (lid off), turn the heat to high and bring to the boil (will take 8-10 minutes). Once it has reached boiling point, turn the heat down to medium (bubbles at edges but not bubbling in the centre) and put the lid on. Now cook the jam allowing it to thicken and reduce stirring regularly over a 40 minute period. When the 40 minutes is up, remove the lid, stir and give the jam a final 10 minutes of cooking so that almost all of the liquid is absorbed with the jam having a thick chunky texture.
To serve: once the jam has cooked, turn the stove off and let it cool. Then portion the jam into a sealed, airtight container. Serve it on a grazing platter, cheese board, condiment for meats, dip or spread. It needs to be refrigerated for storage and will last 5 days in the fridge.
