I love BBQ...chicken, steaks, burgers, chops, shrimp, you name it, but my favorite is barbecued pork ribs. I especially love it when the meat is falling off the bone tender with a smoky tangy sauce. The best ones are cooked slowly over a low wood fire for hours and hours until they are meltingly delicious...but who has time for that?!?
Perpetually in a hurry and looking to do more in less time, I've experimented over the years with ways to accelerate the process of getting all-day-bbq results in an hour or so. I'd read about people pre-boiling their ribs to get them cooked and start the process. After trying that, I found it still took over an hour of boiling to make a difference, and that even when I mixed spices into the water, the ribs lost flavor.
Then I tried starting them in my trusty pressure cooker, which is like magic. If you don't have a pressure cooker, get one! They save energy, time, and produce fantastic results. This is all because the temperature inside these pots gets much higher, up to 260 degrees, versus a maximum of 212 degrees when boiling in a regular pot. The other nice feature of a pressure cooker is that the foods can effectively be steamed rather than immersed in cooking liquid, allowing them to retain more of their original flavor.
So here's how I put all that kitchen science to work for me. I salt and pepper a rack of ribs and pressure cook for 20-30 minutes. For added flavor, I mix 1 bottle of beer with 12 ounces of water as the cooking liquor. After about 25 minutes the meat will be tender and pulling away from the bone.
As a second step, I slather the ribs with a favorite BBQ sauce, then put on my gas grill on high for 15-20 minutes. For an added smokiness, I put wet wood chips into a foil pouch, poke holes in it, and throw it on the grill with the ribs. At a good high heat on a gas grill, the sauce condenses and the sugars caramelize while absorbing the smoke very quickly.
With this approach, you get "rib shack quality" ribs in about an hour!
