It is most definately worth seeking out the Chervil Root. This root vegetable looks like a small, squat parsnip. It can be cooked as potatoes – but it is just so much nicer. It is simply splendid roasted. It causes great joy.
Another vegetable that is worth a bit of hunt – it seems to have become rather rare – is salsify. This root vegetable has to be peeled and does suit being boiled then rolled in a little butter. After peeling it rapidly turns colour, so a squeeze of lemon juice may need to be at hand.
I have found both these vegetables in Natoora – a wondrous shop containing all sorts of stuff we don’t normally see in the UK. It also stocks a large variety of saucisson/salami type sausage that contain an absolute minimum of preservatives.
