We made this in the pizza oven and they were delicious!
1 rack of pork spare ribs
6 t. chopped rosemary
3 t. minced garlic
1 12 oz jar of orange marmelade
1 T. cider vinegar
Rinse the ribs and pat dry. Place the rack on a sheet of heavy duty foil, large enough to wrap the ribs. Sprinkle them with 4 t. rosemary, 2 t. salt, 2 t. garlic. Wrap them with the foil, meaty side down, and make an airtight seal. Transfer them to a baking sheet and roast them in the pizza oven at 600 degrees for 1 hour and 10 minutes (turning it half way).
Meanwhile, for the glaze, whisk together the marmalade, vinegar, 2 t. rosemary, 1 t. garlic. Cover and set aside.
Once the ribs are done, unwrap them and place them onto a baking sheet lined with foil and topped with a cooling rack. Generously brush the marinade on top. Place them back into the oven, uncovered, until the glaze starts to bubble and brown. This will only take a couple of minutes. Once out of the oven, cut them and serve them on a platter lined with rosemary sprigs.
