Boil a bunch of chopped potatoes in a big pot of boiling chicken broth. When the tomatoes are cooked, add some milk, frozen corn, cayenne, thyme, mustard, and salt to taste. Heat through and serve. I usually just make enough to fill a 3-quart pot; fill the pot about 2/3rds full of potatoes and don't add too much water/broth- just enough not quite cover the potatoes, or even less. Add enough milk and corn to fill the pot.
