it's proving for the second time - it's a flat-ish square/disc (let's not worry about shape...) and its on an oiled baking tray. I'm mystified as to what I'm meant to do with cling film (if anything....) if I cover it - wrapping the clingfilm over the egdes of the baking tray, surely that'll constrain it and stop it rising. So I've kind of put cling film losely over the dough - did I do right? - recipe is unclear
