All the advice here about pork steaks has been good. They are a St. Louis tradition.
Traditional way (in fact, the way I cooked ours yesterday) is as follows:
1) Start charcoal in Weber kettle, medium heat, indirect method; open a Budweiser.
2) Make sure the Cardinals are on the radio
3) Season pork steaks with salt and pepper, or use a seasoning mix (I like Riley’s); have another Budweiser.
4) Grill slowly on each side until brown; on the hot side of the grill.
5) Place pork steaks in a heavy duty foil pan, add some barbecue sauce (Maull’s, a St. Louis brand, is best for this) Add a bit of Budweiser or water to thin the sauce a bit. Cover the pan with foil, and place it back over the Weber, indirect (this is important)
6) Bake in the covered Weber over low heat for about 45-60 minutes; or until very tender. The Weber should be at about 250 degrees. Enjoy Budweiser as appropriate. Cheer for the Cardinals.
7) Enjoy your pork steak dinner with a baked potato and corn on the cob.
It’s not real Southern style barbecue, but it’s extremely good, low maintenance, and cheap. Our kids just love them. Great for a crowd, and because they are just tenderizing and continuing to stay warm over low heat, good if your schedule for dinner needs to be flexible. The leftovers make great sandwiches or can be used as a base for burgoo or Brunswick stew.
Another St. Louis tradition is to cook brats the same way, in barbecue sauce. Now, I don’t care for that as much, as I like brats with mustard.
St. Louis style sauce, like Maull’s isn’t as thick or sugary as a KC style sauce like Masterpiece. It’s thinner, a bit more vinegar.
Don’t try this with pork chops, they will dry out. You must have the blade steaks, as cut from the butt roast. Don't worry about the fat, if you've cooked them properly, the fat melts out.
