Fish

Put potatoes and carrots together in a small saucepan, add salt and water. Cover and cook gently until tender. Remove from heat, but do not drain. Meanwhile, saute onion in butter for 3 minutes. Blend in the flour until smooth and add milk gradually, stirring over medium heat until the mixture boils and thickens. Discard skin from salmon, crush the bones, and flake the fish.
