thank you for the recipe for the rub, elfie!
and thanks for all of the info, everyone!
i'm going to make this tonight, let it sit in the rub overnight, then cook it tomorrow as i begin my vacation. something to nibble on for the week.
i'm thinking of starting it on a lump hardwood charcoal grill, then finishing it in a crock pot over onions. i don't have the time to watch the grill for hours, and i don't want the oven on in the house all night, so it's my best plan so far.
i'm not sure if i should use indirect heat on the grill by putting the coals around the outside and a pan underneath. i'll probably only be able to keep it on the grill for an hour, or maybe two. i want char, but not burned.
then, i'll put it in the crock pot overnight. i think i'll add a little apple juice to the sliced onions that i use to set the roast on in the pot.
i won't get a decent bark doing it with this method, but it's more convenient.
