Good BBQ doesn't need sauce. I coat most meats with my Memphis style sweet heat rub. When I smoke prime rib it's just course black pepper and salt with granulated garlic. Fish gets a little garlic, onion and cayenne powder into the brine. Standard brine for fish and poultry is 1C salt, 1C brown sugar and 1/2C apple cider vinegar to 1 gallon water.
