English muffins are an old type of bread roll that are quite popular in the English-speaking world. Do not confuse them with the American cake-type thing of the same name. It came as a surprise to me to learn that they are griddled (cooked without oil on a hotplate) rather than baked.
Semolina for dusting. You can use active dried yeast instead of fresh - use one third of a sachet for the starter, and the rest for the main dough.
