As an English chap, just like to say that a crumpet is definitely not an English muffin.
Have them toasted with lots of butter. Butter not margarine or a vegetable spread, proper butter is the only option!
A crumpet is also not a pikelet; they are like a hybrid of a pancake with a drop-scone.
Just read this whole thread and no one mentioned it so belatedly feel I have to mention that growing up we had toasted crumpets topped with butter, strawberry jam and slices of cheddar cheese — at the same time. So there’s this option too.
Mmmm. Love me a crumpet. It's been years since I had one. There used to be a place nearby (Carmel, CA) that made fresh crumpets, but they went out of business.
