Place in a large pot of water with vinegar, make sure ribs are covered with water.
Bring to a boil and lower heat to a low boil for one hour.
Remove ribs from water.
Cover with BBQ sauce.
Place on grill until sauce firms up and the ribs are heated through and you have some nice grill lines. Can also be placed under the broiler in the oven.
Notes
If you want to keep your grill clean, lay a piece of aluminum foil on the grill and then add the ribs to the grill. Easy cleanup!
The friend who shared the recipe told me that her kids have even eaten these easy bbq ribs without putting them on the grill. They are so tender when they come out of the water you can just add sauce and eat! I love the flavor the grill adds.
