Place the washed leeks into a tray lined with parchment paper, drizzle over the oil and seasoning, and place in a hot oven at 220c to cook until well charred for approx. 30 mins.
Once ready and almost black all over, place in clingfilm together so they sweat and leave to cool.
Chop up finely, place into blender and add the butter in.
Chill the butter before use.
