In a bowl, whisk all of the ingredients together until well combined.
To use: Pat the steaks dry thoroughly and place in a 9-by-13-inch baking dish. Pour the marinade over and turn the steaks to coat. Cover and refrigerate for at least an hour or up to overnight. (Alternatively, you can place the steaks and marinade in a ziplock bag, seal and squish around to coat the meat with the marinade.)
When ready to cook, remove the steaks from the marinade; pat off excess. Sprinkle with salt. Cook as desired.
