Place potatoes, onions, celery, and salt in the 4 c of water in a large pot. Simmer about 15 minutes until vegetables are tender. Put in blender and puree until chunky. Return soup to pot and add half-and-half, butter, and cheese. Simmer until hot. Do Not Boil.
this makes a very good soup. Michael S. of Murrieta sent in the same recipe."
