Boil up a couple of peeled, chopped baking potatoes with a stick of chopped celery. When all tender and the water is almost gone, slowly stir in about a cup of whole milk, a cup of grated cheddar cheese, stir to melt. Add a cup of sour cream. Heat slowly once you add the sour cream. You can add more milk if you wish. Salt and pepper to taste.
This recipe is from a dear soul I was blessed to know some years ago.
