Did turbo babyback ribs last night and wow.... Super impressed. I'm not sure how well this would work with spares but it turned out some excellent babybacks.
We don't like mushy/greasy meat, and that is usually how foiled stuff turns out. I try to render or cook the fat out over the coals before foiling, if I have to foil it's to speed up cooking times. I was skeptical of the turbo style of cooking but only had about 3 hours if we were going to eat ribs last night.
These are what I call eastern european ribs, copied from the wifey's babushka.
Basically 3 parts salt, 2 parts herbs de provence, 1.5 part turbinado or brown sugar, 1.5 part pepper, dash of garlic powder. I sometimes sprinkle in a little bbq rub or mexene chili powder. Never let any seasonings with salt sit on ribs more than a few hours as it starts to turns them to ham.
Cooked 350-375 grate, indirect with plate setter and a couple of firebricks, tiny water pan.
After they got dark mahogany colored, about 1.5hrs I very lightly spritzed with 50/50 cider vinegar and apple juice, let them set up for 10 min, and lightly foiled bone side up with maybe 1tsp of spritz for 1hr.
Then opened the foil and finished naked for 30 min, basting with drippings from foil.
These were quite possibly some of the best babybacks I've done. Usually they seem a little greasy to me, but I suppose cooking them at high heat renders the grease out better than low temps. Now sure how or why. The texture was almost like korean galbi more than fall of the bone. No grease, no fat, but meat had good pull and texture. Maybe a little dryer than low and slow but definitely not dried out like I expected.
I might try turbo spares.. Everything I thought I knew about low and slow bbq is being undone! I don't think this method would cater well to traditional bbq sauced fall of the bone bb ribs, but it's great otherwise. Also thinking the extra fat in babybacks helps them stay moist.
