Boil the potatoes in water until somewhat tender (about 10 minutes), and drain
While the potatoes are boiling, place butter in a large soup pot over medium heat to melt
Add the onion and cook until tender and translucent
Add the potato soup to the tender onions and mix them together
Add the drained corn, cream-style corn, tender, milk, and seasonings - mix well
Fold in drained potatoes
Bring the soup to a boil
Add the lid, reduce the heat and simmer for about 10 minutes, stirring occasionally so the milk does not scald on the bottom
Set out a bowl of shredded cheese to serve with the soup
* the cheese is important, as it is used as a thickening agent
Serve with your favorite crackers or bread
