My wife accidentally used these cubes to make a pot of soup without checking if kp.
I realize last minute but Please advise asap if ok or not.
Thank you
The cubes may be problematic but once the soup was already made any amounts of Chametz in the cubes would be Batel in the soup and the soup can be eaten.
But get rid of any other cubes you still have.
Thank you for the quick reply!
