  1. Melt the butter in a large heavy-bottomed saucepan over a medium heat. Reduce the heat to low and add the onion, rosemary, leeks, garlic and potato chunks, stirring gently. Season well, cover with a lid and allow the vegetables to soften for about 12 minutes without colouring. Give the saucepan a good shake half way through to prevent anything catching on the bottom.
  2. Add the stock and milk to the pan, stir thoroughly and continue to cook for a further 20-25 minutes or until the potatoes are falling apart. Purée the soup in a blender or using a handheld blender, adding a little more hot water if needed to reach the desired consistency.
  3. Return the soup to the pan to warm through. Season to taste.
  4. If you're using the prosciutto, heat a small frying pan over a medium heat. Fry the slices for a minute until they are just crisp.
  5. Ladle the soup into bowls and serve with a slice of hot prosciutto and a scattering of chives.
