I have a good one for ribs, definitely a crowd pleaser. The entire recipe is at

I took 3rd place in a local rib competition with it. The cooking of the ribs is highly modified from the recipe. The sauce is modified to taste, but the rubs are used as specified. Another excellent recipe to play with is the BRITW.
Key West Barbecue sauce goes with. If you use a very high grade cayenne start with HALF the specified amount and after a bit of simmering check again. It will get more and more hot. With standard cayenne, its not that big of a deal. It is a quick sauce, and adjust all ingredients to your liking. I use a bit more of the passion fruit and lemon.
3 cups ketchup 2 cups (packed) dark brown sugar
3/4 cup mango juice or nectar
3/4 cup fresh or frozen reconstiuted passion fruit juice blend
3/4 cup fresh orange juice 3/4 cup pineapple juice
1/2 cup fresh lime juice
1/2 cup fresh lemon juice
1/2 cup grapefruit juice
1/4 cup finely grated onion
1-1/2 tablespoons dry mustard
1-1/2 teaspoons ground white pepper
1/2 teaspoon cayenne pepper
1/2 teaspoon coarse kosher salt
1/2 teaspoon ground cumin
2 tablespoons plus 2 teaspoons cornstarch
Whisk all ingredinets except cornstarch in heavy large saucepan. Transfer 1/4 cup sauce mixture to small bowl; add cornstarch and stir until dissolved. Whisk cornstarch mixture into sauce mixture. Cook over medium-high heat until sauce comes to boil, stirring constantly. Boil sauce 1 minute, stirring constantly. Serve warm or at room temperature.
