Decades ago, Mom would bake boneless country style boneless ribs in the oven coated with BBQ sauce and topped with slices of lemons and onions. The lemons and onions seemed to mop the ribs and also mix with the drippings and baste the bottoms of the ribs as they cooked. What was left from the mostly semi-sour, mostly-dried lemon slices were very good. The onions really added flavor to the bottom basting of the ribs.
I have mostly followed Paul Kirks (author Championship Barbecue Sauce) general recommendations on how to construct a rub. Of the books on barbecue I have found that I keep re-reading his book because of the short section on rub construction. The BTRU rub is good and the rub I will make will be close (don't have cumin). I really enjoy mixing up the rub fresh each time.
This time I think I will try to add a bit more brown sugar (less white sugar). I had some luck with beef ribs last weekend. I applied a (sugarless) basic rub and after everything was coated and laid out on a cookie sheet, I took the time to uniformly sprinkle ?fresh? brown sugar on the ribs and then ?gently? press it in. The beef ribs ended up with a very good semi-sweet flavor without adding much more sugar than normal. I consider a normal rub as roughly equal amounts of sugars and salts.
I am also not sure that I would get a lot of flavor from just placing onions and lemon or lime slices on the ribs. That is why I am considering applying lemon slices about an hour or two before they are the ribs are cooked along with some sort of mop. I think that onion flavor may best come from the mop. Specifically, I am considering making a pork mop made from chopped up bacon, onions, apple juice, bbq sauce and other spices somewhat similar to the one listed in Paul Kirk?s book. I am going to try chopping up some bacon, frying it with minced onions and mixing in the other ingredients.
I guess the goal is a semi-sweet rub balanced with a semi-smoky onion mop balanced with sour citrus tang from the lemon/lime slices. I am still in the planning stage and if it seems like it is getting too complex; well, I do have rum. As long as I DO NOT overpower anything I think it will work out.
Why I am doing this is because it sems that country style ribs do not seem to have as much flavor as baby back or spareribs or cook-up as well . Country style ribs do have more meat and cost much less but seem to need a bit more assistance and flavor enhancement than just a rub. Just IMHO. Something to try.
