1.5 pounds sliced bacon, cut crosswise into 1-inch pieces
2 Medium yellow onions, diced small
3 garlic cloves, smashed and peeled
1/2 cup cider vinegar
1/2 cup packed brown sugar
1/4 cup cane syrup
3/4 cup brewed coffee
Directions
In a large skillet, cook bacon over medium-high, stirring occasionally, until fat is rendered and bacon is lightly browned about 20 minutes.
With a slotted spoon, transfer bacon to paper towels to drain.
Pour off all but 1 tablespoon fat from skillet (reserve for another use); add onions and garlic, and cook until onions are translucent about 6 minutes.
Add vinegar, brown sugar, maple syrup, and coffee and bring to a boil, stirring and scraping up browned bits from skillet with a wooden spoon, about 2 minutes.
Add bacon and stir to combine.
Transfer mixture to a 6-quart slow cooker and cook on high, uncovered, until liquid is syrupy, 3 1/2 to 4 hours.
Transfer to a food processor; pulse until coarsely chopped. Let cool, then refrigerate in airtight containers, up to 4 weeks.
