Back to the OP: "Have you made your own crumpets? "

Yes, I did, once. Here in the U.S. a crumpet is sold as an English muffin. One day, intrigued by the name, I made crumpets from a cookbook. After all the work, they were just English muffins - rather tough, kind of sour, and full of holes. Mine were not different from the supermarket variety.

The best thing about a crumpet is the butter that fills up the holes and the jam or jelly on the top. Years ago we made green-tomato jam from the Nero Wolfe Cookbook, and it was great on toasted crumpets. But I don't eat that kind of food anymore. Sigh.
