Steve, I just have to thank you for coming up with a very delicious and versatile sauce. I've made the lexington and a few variations and have had great success with them.
I amended it to my tastes by substituting soy sauce for worstershire and chipotle powder for cayenne, and by removing the celery seed, but the original was an excellent starting point.
I recommend to everyone that hasn't tried Steve's lexington give it a whirl, it works very well with ribs, pulled pork, chicken, and bbq spiced grilled pork loins - and I'm sure the possibilities are as endless as you care to make them.
