I use a round beverage cooler. It's made to hold and serve liquid from and the inside is pretty hard plastic. Other coolers are made to hold ice and food or canned drinks, so the plastic walls never touch the food. My rectangular cooler def has softer plastic inside. Just some observations but this is one of the reasons I went with the Bev cooler. Plus, easier to stir. Who uses a rectangle or square pot? J
