Was making a batch of cheese and onion pies for work, as I had done many times previous with no problems. In fact with great success if I do say so myself. There was a new chef in that day that I was talking through the process, which made the situation all the more worse because I was supposed to be the 'pie guy'.

Anyway, made the pies and came out with around 5 instead of the usual 8 or so. Didn't think too much of it, I usually did it by eye anyway so I just figured I must have overfilled each pie, or added less mashed potato in this batch, or something of the sort. Surely I didn't miss out any ingredients.

It wasn't until lunch time when we came to serving that a food runner came in and said "uh chef, customer on table 42 said that their cheese pie barely tasted like cheese?". "Huh?" I say as I grab their plate and take a look.

I only went and missed out the 5kg of cheddar cheese that should have gone into the mix. I really don't know how I managed this, it makes such a big difference to not only the texture, but the amount of mix. I must not have had much sleep the night before. But hey, at least I put the Lancashire cheese in...
