Found a really good way to cook deer ribs.I seasoned them,then browned both sides with a little olive oil ,a few pieces at a time.Then I stacked the ribs in my cast iron dutch oven and put them in the oven at 375 degrees with the lid off for about an hour until all the pieces looked nice and brown.Then I sliced some onion and put it on top the meat and continued cooking for another half hour until the onion looked like it was starting to look slightly done.Then I added a cup or so of water and put the lid on and continued cooking.Checked occasionally and add a little water as needed.Cooked them about 4hrs.They were moist and fall off the bone tender.

For many years the guys in the camp where I hunted didn't even bother with the ribs. I used my filet knife to slice the meat from between the ribs, sometimes I smoked it and sometimes I made jerky out of it. Either way it was good eating, lately my BIL has been leaving the meat on the bone and smoking the ribs. Turns out great and there are never any leftovers.

good on you for figuring out a way to use them.
