Go on, admit it. In your cutlery draw do you have special "fish" knives and forks? Go on, do you?
We used to. Hilary would always insist that this was a necessary feature of a full "canteen" of cutlery. We managed to get through several sets of these (you know we lost three forks, two knives, and a couple of spoons got broken, so we had to buy another) before I plucked up enough coursge to tell her about "fish cutlery" business. Fish cutlery was used by the aristocracy. It was used because their usual silver would tarnish if used for fish. It would tarnish because our rather inbred aristocracy of limited intellectual ability, could imagine no other way of eating fish other than with a slice of lemon. And the acid in the lemon would tarnish the silver cultery. So you had to have special steel cutlery with which to eat fish.
Now, we have never owned any silver cutlery. I wasn't even born with a silver spoon in my mouth. All of our cutlery has always been stainless steel. Hence we have no need for special fish knives and forks. What about you?
