2 cans beer
1 cup soy sauce
1/2 cup sugar
5 tablespoons vegetable oil
Mix ingredients together and marinade for as long as you like.
I stumbled across this marinade one day when an uncle of mine came over to the house with fresh pork ribs. My uncle requested the following ingredients and threw the ribs in the mixture.
I got the fire for the bbq started, made rice, and brought out a couple of beers from the icebox. (Some argue that I did that in the wrong order: it should've been Beer, fire, rice. They're probably right.)
Since ribs cook relatively quick we didn't have to worry about the fire being too high. The ribs were a golden color, with the pork skin crispy on the outside and moist in the inside, it also had a light sweet yet savory taste from the soy and sugar mixture. Excellent marinade. Simple yet effective.
