The Hairy Bikers combines apples with celeriac to create Celeriac and apple soup with bacon and parsley on Best of British Foods.

The Bikers says: “Eating apples give a sweet note to this root vegetable soup, topped with crisp pieces of bacon and crème fraîche.”

The ingredients are: 500g (roughly 3) eating apples, 50g butter, 1 tbsp sunflower oil, 2 onions, chopped, 1 celeriac, cut into roughly 2cm chunks, 1 large carrot, cut into roughly 1.5cm slices, 2 garlic cloves, 2 medium potatoes, peeled and cut into roughly 2cm chunks, 1 small bunch fresh thyme (3-4 sprigs), 1 bay leaf, 1.3 litres vegetable or chicken stock, made with 1 stock cube, flaked sea salt and freshly ground black pepper.
