White Root Vegetable Soup with Walnuts and Goat’s Cheese (v)
Heat the oil and butter in a large saucepan. Thinly slice all the vegetables and the apple and add to the pan with a good pinch of salt. Cover and cook gently for about 30 minutes, stirring occasionally and adding a splash of water if necessary. Add the stock and thyme and simmer with the lid slightly ajar for 20 minutes.
Cool a little then blend until smooth using an immersion blender or a food processor. Tip back into the saucepan and reheat to serve. Stir in the cream just before serving.
To serve: Ladle the soup into bowls and top with the walnuts, goat’s cheese, a grind of black pepper and a few thyme leaves. Serves 4–6
The vegetables need to be well cooked and meltingly tender at this stage for the soup to have a good flavour.
