REAL soy sauce. White Swan or something quality from an Asian market, not something from the local supermarket.
Creamy peanut butter, any brand.
Cooking Instructions
Combine 1 cup soy sauce with two to three tablespoons of creamy peanut butter and mix thoroughly. The easiest way to make this marinade is to use it when the peanut butter jar starts to run empty. Pour the cup of soy sauce in the peanut butter jar and shake during an entire episode of your favorite sitcom and then pour over fresh beef. Ligthly cover and put in 'fridge, turning occasionally over the next hour or so. Then cook the beef and amaze your friends and neighbors with the delicious taste!
