Hardly ever seen until this year but now it's trendy and on every menu. It grows like a weed in my garden. My favourite way to use it is to rub my salad bowl with a big handful of the stuff and it will impart a lovely savoury Bovril like flavour. When used raw in dishes it can be very overpowering. The first young stalks of spring are the best for a delicious delicate flavour.
