I cook from scratch a ton, but using canned beans like Bush's as a starter base is not only a real time saver, but the results are often indistinguishable from home-made. I don't mean just straight canned beans, but doctored up with some of your rub, some molasses, sugars, chilis, onions, herbs & spices of choice etc.
When I'm throwing out a spread of Q, my meat is my main focus (and time consumer). Especially when my canned but doctored baked beans are delicious.
