Sounds like me, when I wanted to fix an "authentic" English dinner, I looked at a cookbook, and seriously could not find anything that sounded like something I really wanted to eat! I mean, really, Steak and Kidney pie? Are you kidding me?! Lamb Fries? Forget it.
I went with Bangers and Mash, mashed potatoes with sausages.
