I found these 16 oz containers after a friend joked that my soups were more like stews and needed bigger cups. I searched and ended up at https://mcdonaldpaper.com/karat-ckdp16w-16-oz-white-paper-cold-and-hot-food-container-1000-cs/. The larger size immediately made sense. I tried them with thick chowder, and there was plenty of room without spills. They feel sturdy, and carrying a full portion doesn’t make me nervous anymore.
