I first tried this recipe at the Hershman's and it was tender and juicy. It was so delectable, the English demanded we tell the world about the only English food worthy of mention - besides fish and chips, but anyone can do that.
This was from the kitchen of Dean's mom, Nancy Hershman, and she found it in a Playboy magazine back in the 60’s featuring one of here sorority sisters. Someday I'd like to verify this claim.
This is the original recipe I got from Dean, but I'd like to try an overnight marinade to help tenderize and flavor the meat. Here's a take from the food network and one from All Recipes that suggests the marinade.
Steak
Mustard Seasoning
Butter Sauce
