I snagged this recipe from the Food Network, and tweaked it a little, mainly substituting natural sweeteners for all the brown sugar. It came out SUPER (actually, it's vaguely redolent of those naughty BBQ potato chips we all secretly love).
BBQ Sauce
3 T unrefined sea salt (NOT table salt!)
1 T chili powder
1/2 tsp. black pepper
1/2 t cayenne
1/2 t jalapeno seasoning (I use extra chili powder for this)
1/2 t Old Bay seasoning
1/2 t thyme
1/2 t onion powder
2 T garlic powder
2 T lard (or bacon fat)
1/2 cup white wine *NOTE: recipe updated 1/2/11. See comments below.*
2 T vinegar
2 T Worcestershire sauce
3 T honey (I recommend raw)
7 T maple syrup (I recommend grade B, organic)
1 T molasses (I recommend Blackstrap)
*NOTE: do not cut down on the amount of sweeteners or the balance will be off. If necessary you can use all honey in place of the maple syrup and molasses.*
Combine all and reduce over low heat until thickened, stirring frequently. Pour into a jar or small pitcher and store in the refrigerator, covered with plastic wrap. If you store it in an oven-proof pitcher like I do, you can stick the pitcher in the oven for a few minutes while the ribs are cooking to soften it, then use what you need and refrigerate the rest; repeat indefinitely.
This will refrigerate well and get your family through many meals of ribs! To cook spare ribs, simply place ribs on a baking sheet and cook at 400 degrees for about 10-15 minutes, depending on thickness.

You may turn them over once during cooking if you like. Remove from oven, slather with BBQ sauce, and cut ribs apart. Get ready for a succulent and delicious taste experience! Serve with cornbread and greens, or with sweet potato fries, or even just a simple acorn squash, cut open, cooked in a glass baking dish face down (in 1-1.5" water), and filled with butter.

Make sure your pork spare ribs are sourced from a small local family farm. Contact me if you would like information about sourcing in NYC. **NOTE: PLEASE AVOID USING BEEF SHORT RIBS FOR THIS RECIPE! They need to be cooked a very long time, and I cannot speak for the suitability of this sauce for short ribs cooked that way. Go for the pork spare ribs.
