Combine all ingredients (except for shrimp) in a saucepan and bring to a boil, stirring constantly.
Split sauce into 2 bowls, one for brushing your cooking shrimp and one to use for a final brushing at serving.
Skewer the shrimp, brush with some of the sauce, then grill over medium-high heat, keep basting the shrimp with the sauce until cooked. Depending on the size of shrimp you use about 2-3 minutes per side. Watch for flare ups...the honey and molasses with excite your grill!!
If you are big into dipping shrimp in sauce make extra sauce...increase recipe by 50% and dip away!
