yes
Yes, you can store soup in a stainless steel pot, but it's best to transfer it to a container with a lid for longer storage to prevent the soup from absorbing any metallic flavors from the pot. Stainless steel can react with acidic foods like tomato-based soups over time.
For serving soup, use bowls or mugs. For cooking soup, any sauce pan, dutch oven or stock pot large enough to hold the amount of soup you are cooking is fine. To store soup in the refrigerator or to freeze it, put the soup in an airtight container suitable for the fridge or freezer.
You can use an immersion probe to check the internal temperature of a pot of soup. You can also use a thermocouple with a surface probe to check the internal soup temperature.
yes by pouring nonscorched soup into fresh pot but you must be careful to not let scorched soup soup into the new container
Steel, Copper and Aluminium pots
As soon as the refrigerator can take the heat. Its best to put the soup in another container while its hot or cooled off a little then store it. Dont let it cool off then store it, since its safer to go from really warm to refrigerated.Split the soup into smaller containers so the soup is less than 3" deep. Then put the containers in the fridge. Before doing that, you could put the pot of soup in a bowl of ice or ice water to help quickly chill the soup. Stir the soup as it cools so the center does not remain hot.
I don’t know
Sure, you can store soup in an aluminum pot, but I wouldn't recommend it for long-term storage. Aluminum can react with acidic foods like tomato-based soups, giving your meal a metallic taste. If you're just storing it for a short time, go for it, but if you want to keep it fresh longer, transfer it to a more suitable container.
As the soup heats it expands (oxygen and bubbles) causing the soup to overflow
probably because it's shaped like an old-fasioned soup pot/cauldron.
As the soup is heated, it expands and takes up more space.
