This is happening today. I did not let it marinate for any time, but i saw many online versions that don't. I also decided to try adding a bit of juice and apple cider vinegar, rather than just water. I did not have dry mustard, so, I did some white grape juice(which has apple juice in it), a bit of the vinegar, a tablespoon or so of dijon, for the liquid. I added a bit of extra sugar to the rub, and any rub that fell off, I added to the liquid mix, and poured all of that in the bottom of the pot. Will see how it turns out.
