Although I eat very little bread these days, I am partial to the odd sandwich or slice of toast if I have a boiled eggy for brekky. It has been considered since time immemorial as the staff of life, yet one thing has always puzzled me. Just who thought up the idea in the first place? At some point in prehistoric times someone must have been passing by a field, noticed the crop and said to himself, "That looks interesting. I reckon that if I let that crop grow a little taller I will be able to cut it down, take off the spiky bits at the top then give it to my wives and daughters to extract the hard bits, grind it to a fine powder, mix it with water and stick it in the oven. next day I shall eat well."
