Buckler Leaf Sorrel and Spinach Soup

Ingredients & Method

For the buckler leaf sorrel and spinach soup

For the sorrel pesto

Make the soup. Heat the olive oil in a large saucepan, then sauté the potatoes, onion and garlic, with the cayenne pepper and salt and pepper added, over a high heat for about 2 minutes or until lightly coloured. Add the stock and bring to the boil, then reduce the heat to a gentle simmer, cover and cook for about 10 minutes or until the potatoes are tender. Add the nutmeg and lemon juice, then remove the pan from the heat.

While the soup is cooking, blanch the sorrel and spinach together in a separate pan of boiling salted water for 1–2 minutes or until just tender, then drain and plunge into iced cold water to ensure they cool rapidly and keep their colour. Drain well and add to the soup, along with the lemon zest.

Carefully transfer the soup to a blender and purée until smooth. If serving the soup cold, pour it into a bowl, then chill over ice in the fridge for about 1 hour before serving. If serving the soup hot, return it to the pan and reheat gently. Taste and adjust the seasoning before serving, if necessary.

Meanwhile, make the sorrel pesto. Toast the pine nuts and linseeds in a hot, dry, non-stick frying pan over a high heat for 2–3 minutes or until golden brown all over, stirring. Remove from the heat and leave to cool completely. Once cool, place the toasted pine nuts and linseeds in a blender, along with all the remaining pesto ingredients and blend together until smooth. Add salt and pepper to taste, then transfer the pesto to a serving dish and leave at room temperature for about 20 minutes before serving, to allow the flavours to develop.

Serve the soup in bowls, either chilled or hot, and serve each portion with a splash of extra virgin olive oil, a few drops of crème fraîche and a dollop of the sorrel pesto. Garnish with edible flowers and herbs and serve immediately.

Cook’s Note

Put any leftover pesto in a clean jar or small airtight container and cover the surface with a little olive oil or place a piece of cling film directly on the surface. Cover and store in the fridge for up to 3 days.
