From the sounds-awful-but-is-really-good files: macca loves to marinate tougher cuts of steak in equal parts Italian salad dressing, ketchup, and Coca-Cola. He lets the steak soak in this mixture all day before grilling. thegolferbitch tried it out, and says it’s both delicious and helps tenderize the meat (the latter’s due to the phosphoric acid in the Coke). She likes a little less Coke relative to the dressing and ketchup, and the addition of some Tabasco.
