In a medium saucepan heat the vegetable oil over medium heat. Add the onion and garlic. Saute until soft and fragrant, approximately 4-5 minutes.

Deglaze with beer, stirring to scrape up any caramelized bits on the bottom. Simmer for an additional 5 minutes.

Stir in the ketchup, brown sugar, apple cider vinegar, cumin, pepper and salt. Stir until sugar has dissolved. Reduce heat to low and simmer for 5 minutes.

Tilt the saucepan and using an immersion blender, blend until smooth.

In a small mixing bowl combine 1-2 tablespoons of cornstarch with 1-2 tablespoons of water. This depends on how thick you want your sauce. I recommend starting with one and then adding another if it isn't thick enough. Whisk into the BBQ sauce until no streaks remain and sauce has thickened.

Use BBQ sauce on ribs, chicken, pork fish or anything else you desire.
