Can you leave soup in a magnalite pot the icebox over night and cook it more next day?

It's generally not recommended to leave soup in a Magnalite pot in the refrigerator overnight. Here's why:

* Aluminum Leaching: While Magnalite pots are made from aluminum, they have a hard-anodized coating that helps prevent the aluminum from leaching into your food. However, prolonged exposure to acidic foods (like tomatoes or certain types of broth) can weaken this coating over time, potentially increasing the risk of aluminum leaching.

* Temperature Fluctuations: Storing soup in a pot in the refrigerator can lead to uneven cooling and potentially create an environment where bacteria can grow.

* Flavor Change: The flavor of the soup might change after sitting in the pot for an extended period.

Here's a better approach:

1. Cool the soup quickly: After cooking, transfer the soup to a shallow container (like a glass bowl or Tupperware) to cool it down rapidly.

2. Refrigerate: Once the soup has cooled, cover it tightly and refrigerate.

3. Reheat in a different pot: When you're ready to reheat, transfer the soup to a clean pot (not necessarily the Magnalite) and heat it on the stovetop.

By following these steps, you'll ensure a safer and more flavorful result for your soup.
