I have a large meaty pot in which it is easier for me to cook soup in. If it hasn’t been used in the past 24 hours can I eat this soup in a milky meal?
Thank you for your question.
A pareve soup that was cooked in a meaty pot may be eaten with a milky meal, however the Ashkenazi minhag is that we don’t eat it together with milk i.e. put milk in the soup. Regarding your specific question, since the pot was not used within 24 hours, according to some poskim, you can even eat the soup together with milk, however this is controversial if. If it is hard for you to use a different pot, then you may even use the pot for the pareve soup and eat it together with milk.
To sum up, you may use the pot to cook the soup, if it won’t be eaten together with milk. If you are planning to eat the soup with milk, it is controversial and if it is hard on you to use a different pot, you may use the meaty one.
