1 pound thick-cut bacon, sliced into small pieces
1 small red onion, finely diced
2 cloves garlic, minced
1 cup fresh blueberries
1/4 cup brown sugar
1/4 cup strong brewed coffee (cooled)
1 tablespoon lemon juice
1 teaspoon lemon zest
1 teaspoon fresh thyme leaves
Cook the bacon in a large skillet over medium-heat until crispy, then remove it with a slotted spoon, and set it aside.
Leave 1 to 2 tablespoons of the rendered fat.
Add diced red onion to the pan and sauté until soft and caramelized, 8 to 10 minutes.
Stir in the minced garlic and cook for an additional minute until fragrant.
Add the blueberries, brown sugar, brewed coffee, lemon juice, lemon zest and thyme.
Stir to combine, and bring to a gentle simmer, allowing the sugar to dissolve and the berries to start breaking down.
Return the bacon to the pan and reduce the heat to low.
Let it simmer for 15 to 20 minutes, stirring occasionally, until thick and jammy.
Let it cool slightly before transferring to a jar.
