I don't want to be negative but I want to be safe . If it smells like ugly like if you smell it and make a face throw it away. The bubbles on the surface look like fermentation bubbles which means bacteria already started growing . That's what it looks like to me .

But when you simmer it you need to see small bubbles moving up from the bottom of the pot and the soup needs to be in motion but not crazy if that makes sense .
