Correct, the texture is entirely different too. English muffins are immediately discernable as a baked product, crumpets are a pan-cooked product, whose main characteristic is the vertical holes that soak up butter and jam to turn the crumpet into a squidgy mass of sweet mush - perfect comfort food. I would think every supermarket and most corner stores would carry both muffins and crumpets in Australia and New Zealand.
Titch is an inspirational cook, these are photos worthy of the national archive. He deserves to get his own radio show, like Click and Clack, the Tappet Brothers.
The triumph of the ordinary!!!
