Diane's Clam Chowder

Cube 3 large potatoes and 1 medium onion into a large dutch-oven style cooking pot. Add enough water to barely cover vegetables and cook until tender.

Add, undrained and bring to boil:
2 cans creamed corn
2 cans minced clams
2 cans evaporated milk

In a small saucepan, melt 1 cube of margarine then add 1 cup flour and salt and pepper to taste (or chicken or clam base). Ladle just enough soup liquid to make flour mixture pourable then add back to soup to thicken. Continue cooking, stirring constantly, for 1 minute.
