Iceberg lettuce is one of the great horrors of modern life.
It is not actually food, of course, any more than plastic parsley in a butcher's shop is real food. It is the necessary corollary of the mushiness of most fast 'food'. It is a global brand worth a May Day riot on its own tasteless account. Yet supermarkets sell more of it than all other kinds of lettuce put together. A depressing percentage of the population under 30 are unaware that there is any other kind of lettuce, and yet lettuce has been cultivated for thousands of years with dozens of varieties available.
