Thank you, Secret! I'm a transplanted Tulsan who fondly remembers having this dish at Bishops in downtown Tulsa on Sundays after church with the family. I was cruising 'zaar today looking for something different to do with ground beef, and on a whim typed in 'Brown Derby', and there it was. This is a unique recipe that made Bishop's famous. You made my day!
I got this recipe from the chef at Bishop's when I was a teenager. This is accurate, but the chef was very clear that the roux for the Diablo sauce had to be made with real butter. He made the sauce up a vat at a time, so the A-1 and other sauces provided in my recipe were by the bottle.
Bless you Gingerbear for finding and sharing this lost recipe for Bishops one of a kind Brown Derby with Diablo Sauce which I had as a child in Tulsa but have never forgotten. Now thanks to you I can re-create this feast of the dish and I urge everyone who reads your recipe to try to do the same. They will not forget it either. All of us who appreciated Bishops unique recipes and dishes are grateful to you for reminding us that they're still possible to make. UNFORTUNATELY NO ONE MAKES THEM LIKE THIS ANYMORE. I will drink a toast to you Gingerbear. Thank you, melpreisz
