So, turns out I killed the yeast by using too hot water. Should have been warm rather than hot. Didn't rise at all. But, I went ahead anyhoo, rolled it out and it was actually lovely!! I ended up pricking the base and didn't pre- cook at all, just loaded up with cheese, sweetcorn and mushrooms and it was really nice.
Very impressed. I'm going to try rolls next time. Here's to hoping I'm more successful with the yeast!!!
Thank you
