Yep, Jos, you're right. By the time I began cooking the test crumpet, time was getting away. It would have been brunch and not breakfast, so I didn't go back to read that bit of advice. The holes were forming, but not many. It seems counterintuitive to make the batter less stiff so that the holes would form better because the holes were forming and then filling up again with runny batter, but also I think I put too much batter in the first one so it was too thick.

I'll make some more soon and see if I can get it right. This might be my project for the rest of 2021.
