Preheat your grill or oven to 300°F (150°C). Prepare the ribs by removing the membrane from the back of the ribs for better tenderness (use a knife or paper towel to help grip and peel it off). Season the ribs on both sides with salt, black pepper, and any additional seasonings you prefer. Wrap each rack of ribs in aluminum foil, creating a tight seal to keep the moisture in during cooking. Place the foil-wrapped ribs in the preheated grill or oven. Slow-cook the ribs for about 2.5 to 3 hours until they are tender. You can check for doneness by poking a toothpick between the bones – it should slide in easily. Once the ribs are cooked, carefully remove them from the foil and brush a generous layer of BBQ sauce on both sides. Place the ribs back on the grill or in the oven for about 10-15 minutes to allow the sauce to caramelize and create a nice glaze. Keep an eye on the ribs to prevent burning – you want the sauce to caramelize, not char. Remove the ribs from the heat and let them rest for a few minutes before slicing. Slice the ribs between the bones and serve them with additional BBQ sauce on the side. Enjoy your finger-licking BBQ ribs! Serve the ribs with your favorite BBQ sides like coleslaw, cornbread, or baked beans for a complete meal. Feel free to adjust the seasonings and cooking time based on your preferences and the equipment you're using.
