A good thought bluecheese, I may have to go and buy another piece
I think I drained the curds a bit early, quite a lot of solid matter went straight through my collander. When I looked in the bin with the whey in it this morning there was a "cheese" floating in it It was very fragile and broke up as I lifted it out but it was several pounds in weight that had coagulated and come together in the whey overnight. I should have taken a photo. The bits are now on top of the rest of the curds and weigh in at hefty 5kg all told. Obviously a fair bit of that is still water! I'm going to salt it and redistribute the curds into a mould later on.
