Never one to let meat go to waste, Hugh transforms leftover lamb's lungs into a spicy Asian soup recipe in River Cottage Spring
1.Detach the lungs from the pluck. Trim and cube the lung in to 2- 3cm square pieces removing any sinew or ventricles as you go. Take 100g of the lung and rinse it well. Place in a saucepan covered with some stock vegetables- see the recipe for devilled crab for more details. Place a plate on top of the pan to weigh the lung down. Bring to the simmer and cook for about 1-1.5 hours, or until the lung is tender. Set aside to cool. Discard the cooking liquor.
2.Put the ginger, lemongrass, garlic, kaffir lime leaves, coriander stalks, chili and water or stock into a saucepan. Bring to the boil on medium heat for 5 - 8 minutes then strain the liquid into a clean pan.
3.Cut the lung into 1cm square chunks, checking once again for sinew, then add it to the soup along with the noodles. Continue to cook on a medium heat, covered, for about 2-3 minutes.
4.Remove from the heat and add lime juice, coriander leaves and spring onion. Season, stir well and serve.
