Starting with about 4 or 5lbs of thawed, well-trimmed meat--dissolve about 2/3c brown sugar and 1/8c coarse salt in half gallon of water and chill the water. Put the meat in the solution and add more water if you need to cover it. Let it sit in the fridge or freezer for an hour. Take it out and rinse/slice it. Now: 1c brown sugar, 1/2c worcestershire, 1c water, 3tblsp coarse ground black pepper, 3tblsp coarse salt, 2tblsp each of cure- chili powder- garlic powder, 1tblsp red pepper flakes. Mix everything up in a gallon ziploc and let it soak 12-20hrs in the fridge, mixing occasionally.
That's a pretty good place to start....try it and adjust to your taste.
