This is self explanatory as you can see. You chop up some onions, saute them off in bacon bits while the potatoes are baking. You then take the flesh from the potatoes and add them to this mix after crushing them. Add a little garlic and and a dusting of flour then some stock or water and allow to cook for 30 mins. or so. The mix gets a little thick so milk should be added before serving and also a little cream and chopped chives. This is a great winter soup and a very cheap one.
You should also add some thyme and bay leaf during the cooking as with all soups.
