I have been using a commercial grill sauce called Trinidad Tropical Bake & Grill Sauce from Caribbean Food Products, Inc. For about a year. It is really good stuff. It is blend of citrus juices and spices that has kind of a sweet-sour taste. It is not a pepper sauce and has no heat. I have used it plain, as a marinade for grilling and smoking, and also as a basting sauce. At $3.95 for a 14 oz bottle, it is kind of expensive to use full strength, so I usually use it as an ingredient in my basting sauces. I have not found it on the shelves locally, but many mail-order hot sauce suppliers carry it.

I did 4 slabs of spare ribs yesterday and rubbed them with the Wild Willy rub from the Smoke & Spice book 6 hours before cooking. I made a mop sauce

I smoked the ribs for 6 hours at about 210 using maple logs for fuel. Mopped with the sauce every hour. They looked gorgeous, were very tender and juicy and tasted great! The maple smoke was a perfect compliment for the slightly sweet basting sauce. I got a bunch of maple earlier this summer and have been using it a lot and I really like it. Try the Trinidad Tropical Grill & Bake sauce if you can find it. I think you will like it.
