Someone gave us 50lbs of frozen spare-ribs and I have no idea how to cook them. I doubt I'll cook them all at once! We have a grill, but I've heard you should boil them first. Any suggestions?
Anyone who tells you to parboil ribs should NEVER be allowed to touch or cook a rib... It's a travesty and crime against humanity.
In fact anyone who says crockpot, oven, etc, doesn't know how to make really good ribs and will NEVER understand the difference between their garbage and a truly classic rib. There is ONE way and ONE way only to make truly great ribs... with indirect heat from a fire at about 150-175 degrees.
The ribs are frozen so they are at a slight disadvantage, but the smoke can salvage the flavor...
The best bet is to use a kettle grill or smoker.. but I've cooked ribs in old metal barrels to great effect (the trick is to keep them HIGH above the fire using a direct/indirect method.
I usually use a mixture of lump charcoal (not the compressed nuggets from Kingston... I use a brand called Cowboy Charcoal), Apple chips, Pecan Chips and Hickory. The bulk of the smoke is from the Hickory, with the fruitier wood imbibing a sweet taste and the charcoal giving the flavor true character. Some just use hickory or another fruit wood. Stay away from cedar or oak as they do not flavor well with Pork. Don't use soft woods like Pine as they will impart a very bitter taste. Those are NOT smoking woods.
Thaw the ribs completely. Once thawed, prepare the rib, removing the film on the back (this is a preference thing, btw... you can leave it on). Pat it dry and them coat with a dry rub. You can buy one or make your own... I tend to use paprika, chili powder, dry mustard, and other herbs and spices in mine. The key is to make sure there is NO sugar... sugar burns quickly and you never put on something like a sugary BBQ sauce during the cooking process or your end up with the top layer black as night. I tend to use wood chunks for the hickory and always will let them soak in water, removing them about 10 minutes before I'm ready to sue them.
Prepare the grill for indirect cooking. I'm going to assume you don't have a smoker, or you wouldn't be asking this... To do indirect cooking, you make the wood chips and charcoal into two piles on either side of the grill and the meet will go in the middle. I usually do it 50% hickory/25% Charcoal/15% Apple and 10% Pecan in my mix. Light the fire (avoid using lighter fluid and invest $20 in a chimney starter) and let it burn down to coals. Check the temperature with a thermometer or your hand (5-6 mississippi's I believe) and get it about 175 degrees and put on the ribs.
I recommend checking the thermometer on the Kettle Grill every 30 minutes and keep it in the 150-175 range. The rule of thumb is to add new wood every hour... I add about 6 hickory chunks (depending on how big they are... I like to get them about the same as the charcoal), 3-4 pieces of charcoal and about 1/8 cup of fruit wood chips to each pile of coals. However if the temp falls below 150, add them earlier. I also tend to make a mop sauce and mop the Ribs when you put on new wood. THere are a million recipes out there... I like to put BBQ rub, 3 parts vinegar (I use white vinigar, but want to try Red Wine... not sure if there is too much sugar) to 1 part peanut oil, lemon juice, seasoned salt, dry mustard and a few other spices. I mix them and then boil it with some chopped jalepeno and onion and put it in the fridge and then mop it onto the ribs.
I usually like to cook the ribs for 7.5 hours. My schedule is thus...
Initial Fire - Dry rub only
1 hour - Add more chips - Mop
2 hour - Add more chips - Mop
3 hour - Add more chips - Mop
4 hour - Add more chips - Mop
5 hour - Add more chips - Mop and then sprinkle with dry rub. No more mopping.
6 hour - Add more chips - Pull off ribs. Take a large piece of tinfoil. Sprinkle mop sauce on the foil... not a super lot, but some definite moisture. Put the ribs on top, cover with Foil and make a seal... so the ribs should be wrapped in the foil with no leaks. Place back on Grill
7 hour - Add double the chips - Rake the coals into direct cooking method. Take ribs out of foil. Add either more dry rub, or baste on BBQ sauce. Cook for 20 minutes direct style. WATCH like a hawk and don't let the sauce burn.
Take off, let sit for about 10 minutes or so and then enjoy.
That is how you make great BBQ ribs.
There are MANY methods, but remember any method that boil, crockpot, bake, etc are committing the gravest of BBQ sins and should be avoided at all costs.
