Leek and potato soup

Method

• step 1

  Melt a knob of butter in a large pan with a little oil, add all the leek except a handful and stir. Cook gently until the leek is very soft, this will take about 10 minutes. Add the potatoes, season well then add the stock and bring to a simmer and cook until the potato is soft. Whizz everything with a blender until smooth. Add the cream and season again if it needs it. If the soup is very thick, let it down with a little water, stock or milk. Keep warm.

• step 2

  Heat 1cm oil in a small pan, add the remaining leek and cook until it frizzles. Lift out and drain. Serve the soup and add some frizzled leek to the top.
