Gosh. Those Chicagoans just don't eat like I remember. We had almost 2 tri tip left over. 6+ lbs eaten by 14 people...2 out of towners caught the flu and stayed in the hotel...bummer.
They did love this recipe, smoked then grilled with a mopping and a light rub dusting just before slicing. Gotta thank Tom again for pointing me in this direction. We eat Santa Maria style tri tip fairly often.
