For melt-in-your mouth pork spare ribs, start with homemade dry rub and finish with a final barbeque sauce baste. Recipes for each step of the process follow:

Barbeque Sauce for Pork Spare Ribs

Ingredients:

1 Tbs. butter
1 Tbs. olive oil
1 onion, peeled and minced
4 cloves garlic, minced
1/4-cup peanut oil
3 cups (24 oz.) tomato puree
2 cups brown sugar
1/2-cup Worcestershire sauce
1 oz. white wine vinegar
1 Tbs. chili powder
1 Tbs. paprika

Instructions:

1. Heat butter and olive oil in a large pan over medium heat. The butter should begin to bubble and foam as it heats.
   
2. Once the foam subsides, add onions and sauté over medium heat for five minutes, until just soft. Add garlic and sauté for one minute.
   
3. Add tomato puree, brown sugar, Worcestershire sauce, white wine vinegar, chili powder and paprika and bring to a simmer.
   
4. Cook uncovered until thickened, about one and a half hours.
   
5. Remove from heat, let cool and separate one cup of sauce to be used to baste and three cups to be served as sauce on the side. Refrigerate until ready to use.

This sauce will be used to baste the ribs during the final 10 minutes of cooking time on the barbecue.

Dry Rub for Barbeque Pork Spare Ribs

Ingredients:

2 Tbs. kosher salt
2 Tbs. black pepper
2 tsp. cayenne pepper
3 Tbs. brown sugar
1 Tbs. ground cumin
2 tsp. ground allspice
2 Tbs. chili powder
3 Tbs. paprika
2 tsp. garlic powder
1 tsp. dry mustard

Combine all ingredients and set aside. Placed in an airtight container, this rub will keep for about three months.

Barbeque Pork Spareribs

Ingredients:

8 lbs. pork spareribs, about 3 full racks
1 cup dry rub (from recipe above)
1 cup barbecue sauce, with the remaining 3 cups set aside and served on the side (from recipe above)
aluminum foil
paper bags

Instructions:

1. Prepare the grill: Place a drip pan filled with water in the barbecue — the ribs will cook above it. If using a gas grill, place the pan to one side and only light half of the burners. If using charcoal, get the coals hot and spread them out from the middle, creating a well for the drip pan to sit in.
   
2. Rub pork spareribs with dry rub mixture. Note: It is not necessary to apply the dry rub hours beforehand; applying just before cooking yields the same results.
   
3. Check grill to see if it's reached the proper temperature, 200F. Place ribs on grill over drip pan, close barbecue lid and cook for about 1 1/2-2 hours at 200F. Turn ribs every 20-30 minutes, adding coals or adjusting gas to maintain a steady 200F. Some fluctuation is okay (and unavoidable if using charcoal), but the goal is to stay between 190F-220F.
   
4. Begin basting ribs with sauce in the final 10 minutes of grill time (after about 1 1/2 hours). Any earlier and the sauce will simply dry out. Note: The USDA states that pork should be cooked to an internal temperature of 160F. It is difficult for the meat to retain its juices at this temperature (145F will produce deliciously moist and juicy ribs) but if you are concerned about safety, follow the USDA guidelines and be aware that the ribs will be on the dry side.
   
5. Once the ribs are cooked, wrap them tightly in aluminum foil and place inside paper bags. Set aside for 30 minutes to allow them to steam and tenderize the meat further without overcooking.
   
6. Remove and serve with remaining sauce on the side.
