When I was a teenager people used to ask the philosophical question 'is your red my red?', or in other words 'how do I know that a colour looks the same to other people as it looks like to me?'. I knew that my primary school best friend's blue wasn't the same as my blue, because she was colourblind and could not distinguish blue from grey. Anyway, we never asked the question about taste, but it seems clear to me that we do taste the same food differently, and that your mushrooms are not my mushrooms. After all, if tuna tasted as bad to everyone else as it does to me I don't think it would ever have been recognised as a food.
