Meticulous indeed, bordering on obsessively neat They were all in the same bag, so would have been opened and closed. The recipe called for fresh yeast which was what I used, I think in good date at the time of making the dough but can't be exactly sure, or how well it was stored previously. I will certainly try again, perhaps this time with dried yeast however as this is what I'm most used to. Triangles had the nock cut in which I found very helpful!
