For a long time the only way I’d cook baby back ribs was on my camp chef wood wind pellet smoker. I have cooked around 8-10 racks in the instant pot. I just put about 2 cups of apple juice with brown sugar mixed in. I use a good dry rub on the ribs and let them set at room temperature for about 25 minutes. 35 minuets on high pressure in the ip then pull them out and finish them off with my wife’s secret recipe bbq sauce and 10-15 minuets under the broiler in the oven. They are delicious.
