In a large pan boil potatoes, clelery, clams, and onion until tender. Use only enough water to cover. While boiling, mix in a bowl the milk and flour. When the potatoes are done add the butter and milk and flour mixture, simmer for 15 minutes or until thick.
In the morning defrost 2 loaves of frozen bread. Cut the bread into 3 equal pieces and sit on a greased cookie sheet. Allow to raise for several hours until double or triple in size. Bake 350° for 15 minutes or until golden brown. Cool and cut off the top and take the inside of the bread out. This will form the bowl.
