Step 1

Heat a fry pan to medium heat. In small batches, fry bacon until golden, then remove and drain on paper towel.

Step 2

Clean the pan and return it to medium heat. Add oil and gently fry onions and garlic, stirring until soft and glassy. Add bacon and continue to cook for 2 minutes, then add spices and fry for 1 more minute.

Step 3

Increase the heat to high. Add bourbon and golden syrup and bring to a boil. Simmer for 3 minutes, then add sugar and sherry vinegar. Lower the heat to a steady simmer and cook, stirring regularly, until caramelized and jammy.

Step 4

In a hot fry pan or BBQ grill, sausages for 8–10 minutes, turning until golden and cooked. Assemble in a hot dog bun with cheese, mustard, and lettuce.
