Chef's Ass usually happens in the summer months, when a chef is at their sweatiest. I don't know the medical terminology for it all, but it seems that the salt in your sweat causes some friction on your ass cheeks when they rub together, it feels like a bit of sandpaper is wedged in your ass crack and this burns everytime you move. And before you all start shouting at me to lose some weight. The extraordinary thing is, it isn't just fat chefs that this happens to, it is also the skinny ones.
Now there are numerous ways of trying to cure Chef's Ass. I personally have a shower and then smother myself generously with talcum powder. Others I have seen nip down to the dry stores mid service and get a couple handfuls of cornflour for a bit of instant relief. The best one I saw though is someone came back into the kitchen smelling rather sweet and when asked what he had done he replied
"I found some Birds custard powder and thought it might kill two birds with one stone, curing my chef's ass and B.O at the same time!"At least he was thinking outside of the box!
