Knobbly roots of Jerusalem artichokes have a delicate, earthy flavour that’s a great match for roasts and casseroles. Scrape and steam as you would potatoes. They are easier to peel if cooked first and then allowed to cool. They give an excellent flavour to casseroles and are also very good baked to serve with roast meat.
