Add the chicken broth, potatoes, carrots, corn kernels, and ham concentrate to the pan. Allow the mixture to boil gently until the vegetables are cooked.
Stir in the potato flakes (or mashed potatoes) and milk. Allow the chowder to heat back up, but not boil.
Serve in bowls or large mugs. Refrigerate or freeze any leftovers; reheat leftovers slowly, stirring often, but do not let the chowder boil.
