You don't need to fire up the grill for fall-off-the-bone perfection. Let your oven do all the work; the trick is cooking low and slow.
Start by removing the thin membrane on the underside of the ribs. Take a sharp knife and loosen one corner, then peel the membrane away from the bones.
A wet rub will lock in more flavor and moisture.
Mix together: 1/2 cup maple syrup, 1T salt, 1T garlic powder, 2T quince mustard, 1T apple cider vinegar, 1T Firecracker hot sauce, and 1/4 cup olive oil.
Rub this on both sides of your ribs, then wrap them in tin foil.
Preheat oven to 275.
If you have a cooling rack that fits in a rimmed oven sheet, then put that into your sheet, place the ribs on top, and slide the pan into the oven.
While the ribs cook, make your sauce, recipe here.
Check the ribs after about 2-2.5 hours to see if they are done: unwrap foil, and pick up 1 end with tongs. The ribs are ready when they bend and the meat on top is tender and easily pulls apart.
When done, unwrap ribs, and cover both sides with your sauce.
Place on the wire rack, and return to the oven for 30 minutes.
Remove, turn on your broiler, and brush the ribs with more sauce.
Then broil for 3-4 minutes, or until the sugars start to caramelize.
Let the ribs rest for at least 5 minutes before slicing and serving with more sauce.
Mix the drippings from the foil with what is left of your sauce and serve alongside your juicy sliced ribs.
