MethodFry the bacon inside a large non-stick pan for five-ten mins mins until golden and crisp. Remove having a slotted spoon and transfer to some plate, departing body fat within the pan.
Turn heat to low and prepare the onion within the bacon fat for 15-20 mins until soft and beginning to brown. Stir within the garlic clove, sugar, cider vinegar, bourbon, walnut syrup, coffee and also the bacon.
Prepare gradually for twenty five-half an hour, stirring from time to time until thick and syrupy. Switch off heat, leave to awesome for any couple of mins, then carefully tip everything right into a mixer. Pulse briefly to reduce into small pieces, then leave the mix to awesome before packing it into two sterilised jars. Could keep for approximately 30 days within the fridge.
