Combine all ingredients in a small bowl or measuring cup. Set aside
Pork Ribs
Wash the slab of ribs with cold water and pat dry with paper towels. Remove the membrane on the back side by placing a paring knife underneath the membrane and gently pull it back from one end of the slab to the other end and discard. If it's slippery, you can use a paper towel so you'll have a better grip when pulling the membrane back. (Note: I find that there isn't a difference in removing the membrane, so I tend to omit that particular step). Remove any excess fat by cutting it off with a sharp knife and discard.
Place the ribs in a deep casserole dish or roasting pan. Pour the marinade over the ribs making sure the entire slab is coated. Cover with plastic wrap and allow the ribs to marinate in the fridge for at least 2 hour up to 24 hours. (If marinating for up to 2 ours, flip the ribs over halfway through, so the other side comes in contact with the marinade as well).
After the ribs have marinated, place on the countertop and bring to room temperature. Meanwhile, fire up the grill and when the grill is ready, position the slab of pork ribs on the grill grates with the meat side down and close the lid. Grill on one side for 30 minutes then flip and grill the other side for 30 to 40 minutes.
By this time, the ribs should have a beautiful brown crispy outer coating and no longer pink. Remove the ribs from the grill and place them in a clean roasting pan or baking sheet. Place the ribs in a 330 degree preheated oven and bake for 20 to 25 minutes to tenderize the ribs more. Meanwhile, prepare the glaze.
Glaze
Place all ingredients in a small saucepan and simmer until the glaze has thickened (about 10 to 15 minutes). Add a splash of fresh lime juice and stir. You can tell that the glaze has thickened enough if it can coat the back of a spoon.
Slather the ribs with the glaze. When the ribs have cooled enough to handle, use a chef's knife and cut vertically between each rib bone and serve.
Notes
When preparing the marinade, allow the ingredients to meld together for several minutes to get the flavors going
Marinade for at least 2 hours up to 24 hours
Discard any leftover marinade that has been in contact with the pork ribs
After grilling, place the pork ribs in the oven on low for 20 to 25 minutes to further tenderize
