At that point you are supposed to strain the liquid into a pitcher, but our power went out due to a storm and I didn't feel up to straining in the dark with a flashlight, so we popped the soup pot in the fridge overnight, figuring the power would soon return. It didn't. It hasn't yet!
When I checked the soup in the morning, it was semi-cool, and it had 'heated' all the milk on the shelf with it, so I had to improvise.
It's now on my back deck in the largest pitcher I own, along with several other fridge items, chilling. I have a plan to freeze the stock in smaller portions, in fact I will measure out how much I need for a few upcoming recipes, then I can just defrost it and dump it in.
I can't do all of that until the power turns back on and we go back home. We are at a hotel for tonight. I can't decide what I appreciate more, the heater, or the WiFi.
Edited to add: Finished!
