In summer, use leftover corn-on-the-cob; in winter, frozen, canned, or cream-style corn.
Fry salt pork in soup kettle until crisp. Remove with slotted spoon and set aside. Saute onions in fat until golden. Pour in stock. Add potatoes and corn and simmer, partially covered, 15 to 20 minutes or until potatoes are tender. Add cream, season with salt and pepper, and heat; do not boil. Garnish with reserved salt pork.
