We didn't go looking for barbecue sauce at the new Whole Foods on East Hampden-- but once we found it at the Paradise Barbecue counter, we were hooked. The sauce is haunting, smoky, spicy and sweet all at the same time, just barely thick enough to cling to the meat being dipped in it but never so watery that it becomes a wash. The brick-red color is lovely, the smell intoxicating and stinging, and it's gotten to the point that we'll beg the person working the counter to give us a few little to-go cups so that we can stock our fridge for when we need a fix.
