Heat butter
in medium saucepan. Add onion and green pepper and cook gently 3
minutes, stirring. Add potatoes and water and bring to a boil. Turn down
heat, cover and boil gently 15 minutes or until potatoes are tender. Mix
about 1/4 cup (60 ml) of the milk with the flour until smooth and stir
into the boiling mixture. Add remaining milk, bay leaf, salt, pepper and
corn. Simmer 15 minutes. Discard bay leaf.
Whirl in
blender (half at a time) until nearly smooth. Serve hot or chilled.
