Marc Bittman has a great marinade of soy sauce and bourbon. Its 2/3rds one, 1/3rd the other but i always forget which is which so i take the lazy 50/50 route which works quite well.
Quantities are approximate. Measuring is for wimps.
quarter cup soy sauce, quarter cup Worcestershire sauce, one ounce ketchup, quarter cup duck sauce or apricot jam, 2 tsps garlic, a squirt of hot sauce.
I’m not sure about steak but I’ve done pork tenderloins and chops in Wishbone Italian and it’s pretty good. Has to be the Robusto though and not regular Italian.
Marinate one good sized flank steak in:
1/2 cup lite soy sauce
1 large clove of garlic minced
1 teaspoon ginger
2 Tablespoons sugar
2 tablespoons lemon juice
2 tablespoons oil
1 tablespoon minced onion
1/4 teaspoon ground black pepper
Put in large zip lock bag and put steak in,
let sit for two or three days.(Turn bag at least
once a day)
I cook on a hot grill for just 3-4 minutes per side, but your tastes may be different. I love this recipe.
