I make this marinade for steak tips all summer long and get many requests for it. Figured it was about time I write it down so I can just send people the link. This tastes similar to a mildly sweet BBQ sauce with a bit more complexity. Please do not use diet coke. Only the full flavor stuff will do!
3/4 16oz bottle of regular coke a cola
1 Cup ketchup
4 Tablespoons Ah-So sauce. If you cannot get this substitute hoisoin sauce
4 Tablespoons any brand BBQ sauce
2 Tablespoons Molasxes
2 Tablespoons vegetable oil
5-6 Dashes of soy sauce
Heavy pinch of both salt and pepper
Mix everything together and marinate your steak tips in it overnight.
