sauces, a traditional base for BBQ sauce is
brown sugar, lea and perrens worcestershire sauce (accept no substitutes) garlic powder and parsley, the worcestershire sauce can be increased or decreased for the tamarind bite. This is the base from which all others are made.

Beef
start with the base, add horseradish, pepper splash of wine and a spoonful of woody's "cookin" sauce for hickory flavor.

Pork
use the beef recipe then add copious amounts of mustard and thin with cider vinegar

Chicken
base plus mustard and lotsa louisiana hot sauce. Gotta kill that chicken flavor somehow.

vary the above with anything and everything in the spice cupboard, curry is a good additive to the chicken recipe.
thanx,
