This recipe is for a hot potato salad that contains potatoes, bacon, butter, evaporated milk, green onion, flour, and cheddar cheese. The potatoes are boiled, cubed and mixed with crispy cooked and chopped bacon. A cheese sauce is made by melting butter, stirring in flour, then mixing in evaporated milk and water. Most of this cheese sauce is poured over the potatoes and bacon and topped with green onions, remaining cheese and served hot.
