If you're in the Windy City and in the barbecue mood, this is something to order by the bucket (and isn't that always fun?). Rib tips. They're one of the top sellers at Lem's Bar-B-Q and it's not difficult to understand why. Each tip points to a deep blend of flavors, merging the powerful tastes of charcoal and hickory smoke with the simple sweetness of pork. Lem's tangy, spicy barbecue sauce adds a molasses-colored kick before the tips find their way into a freshly popped paper bag.
