Tried Jeff's rub and sauce this past weekend on some chicken and pork chops (not smoked, but slow/low grilled on the trusty Weber kettle w/a couple chunks of soaked Mesquite). I will have to tame the sauce down some for my family. My brother-in-law and myself thought it was perfect as is, but the rest of the family thought it had too much kick. They all thought it had a great flavor -- just too much hot for them. The flavor of the sauce is incredible and one that I think will be very versatile. I absolutely loved it.
The highlight for me -- being the newly crowned "Master of the Grill" (B.I.L. gave me the new nickname)
-- was my uncle enjoying the chops so much that he bit off and swallowed one of the tines off his plastic fork! I guess that's proof enough for me. LOL!
The recipes are well worth the price, IMHO. The reactions from my family after taking their first bites has more than paid for it already.
