Boil down a bunch of fresh roma tomatoes in olive oil and balsamic vinegar until it's somewhere between pasty and soupy.
Finely chop Jalapenos, Serano chilies, onion, and a bunch of garlic.
In the tomato base, add salt, fresh ground pepper, cumin, coriander, and cayenne pepper to taste.
Add worschestershire (a fair amount, to taste) and whiskey (amount dependent on how much sauce you are making, we use 1 to 1.5oz for BBQ sauce for enough for 3 people).
Add a couple tablespoons of brown sugar, and 2 good squeezes of honey.
Mix well, then add your chopped veggies.
Using large zip lock baggies, put large amounts of the sauce and your ribs (or whatever) into the bags. Let sit in the fridge for a couple hours.
Throw them on the BBQ, slather some more sauc eon top while cooking. Do the same when you turn it over.
Enjoy.
THis is a really good BBQ sauce. The whiskey is a must, by the way. You wouldn't believe the difference in flavor without it.
/edit: Oh yeah, add chopped parsley or basil, if you want.
