I am gutted.
Tried cinnamon buns for the first time today using a Mary Berry recipe. First problem - the dough was too sticky to form into strands so I put mounds on dough on the baking tray.
Next problem - the buggers wouldn't rise, they were supposed to double in size 
Eventually I put them in the oven un-risen. Recipe said they take 30-40 minutes so I set the timer for 30 mins and checked them after 25 - they were burnt 
I now have 20 rock hard things that look like bad Yorkshire puddings. The dds say they're not too bad on the inside, they are being nice!
I have since checked the yeast, said best before a few months ago but as it was dried I didn't think it would matter. Or does it?
Waahhhh. That's 1 KILO of flour plus associated other ingredients I have wasted
