In a large skillet over medium-high heat, cook the bacon just until it begins to brown lightly, about 8 to 10 minutes.
1 ½ lbs. bacon
Once cooked, remove from skillet and place atop paper towels so any additional fat can be absorbed.
Keep the skillet over the heat and remove all but 1 tbsp. of the fat leftover from the bacon.
Sauté the onions and garlic in the skillet until they become translucent, about 5 to 10 minutes.
2 medium onions, 3 garlic cloves
Once the garlic and onions have cooked, add the vinegar, honey, and coffee to the skillet. As the mixture begins to simmer, add in the bacon and give everything a good toss.
½ cup cider vinegar, ¼ cup raw honey, ¾ cup brewed coffee
Remove from the skillet and place in the slow cooker. Cook on high, uncovered, for 3 to 4 hours, until the liquid has reduced and the jam is formed.
Once the jam has cooked through, remove it from the heat and place it in a food processor. Pulse until smooth or desired consistency.
Keep in a jar, refrigerated, for up to 4 weeks.
