My mother shared her secret with me. She adds instant potatoes to her soups instead of corn starch or flour. Works great with Cream of Broccoli and Potato. I never knew why hers tasted better than mine! She also cooks up a batch of regular instant potatoes and then adds one or two potatoes with the skin for a nice "smashed" dish. Microwave makes the potatoes in a hurry.
Adding extra vegetables to a basic homemade chicken noodle soup will add to its nutritional value and enhance the flavor. It will be comforting and delicious.
This is a page about fixing soup with too much pepper. It is very dismaying to prepare a delicious soup recipe only to find that you have accidentally added too much pepper.
