Roast Jerusalem artichoke soup

Jerusalem artichokes are brilliant in purees and soups. In this recipe they are roasted first, which gives a beautiful nutty flavour and also means you don’t have to peel them! Plus less wastage. You can just add some water at the end to lighten the soup or feel free to keep it quite thick and rich. This recipe would also work for chopped celeriac or cauliflower. The roasting gives a depth of flavour that particularly suits the colder months. Serve with buttered brown toast, though it would also work well as a hearty sauce for an autumnal meat or fish dish alongside some chicken legs, duck, or roast monkfish. You could also add some cooked barley or orzo (which only takes a few mins) to turn it into something even heartier. The flavour of Jerusalem artichokes is hard to describe if you haven’t had them before, but I find it very elegant: some bitterness, some sweetness, some nuttiness. Chefs love them but like salsify, their unbecoming appearance has meant they have never really transcended to mainstream popularity in the domestic kitchen. Hopefully this recipe will convince you to give them a try!

600g  Jerusalem artichokes, washed clean
