St. Louis-style barbecue sauce is described by author
Steven Raichlen as a "very sweet, slightly acidic, sticky, tomato-based barbecue sauce (usually made without liquid smoke)".
from wikipedia...i'm not really from St. Louis, more used to KC BBQ style. I like the sweet and a little bit of kick bbq sauces.
KC BBQ is more about variety. we'll cook anything BBQ style with many types of sauces to try. we like our sauces with more molasses than tomato and sweeter with a kick. we're famous for burnt ends (burned tips of the ribs)
