For me, soup is a year-round pleasure. It's one of my favorite foods to prepare and enjoy. The soups I most often make are beef and vegetable (using hamburger), beef noodle (using beef shank bones and egg noodles), and chicken/turkey rice.
Most of the time I only follow the outline of a recipe. I usually add more ingredients than the recipe requires. I recently bought a 9-quart stock pot for this purpose.
