What container do you use to re-hydrate your food?

[DownYonder]

Freezer bag cooked inside a pouch like the one Flake posted. I remove the bag and place in in my pot to keep it from spilling.

Freezer bags =best!!!!!
I do sometimes find that I need to use a cozy to put the freezer bags in to allow them to hydrate...

I use my ti pot. I got lucky, I guess, and bought a Stoic kit from backcountry.com on clearance. Looking at it from the outside, I can't tell a difference between it and the Toaks pots the same size, but mine has non-stick coating in them which makes cleanup a snap.

As has been said, once the food/water comes to a boil, shut it off and let it set (covered) for a while. Maybe turn the stove back for a bit (doesn't take long to bring back to a simmer) after about 5 minutes. Never burned the food to the bottom of the pot this way, so the pot cleans easily.
I, too, use the spoon/ water method to scrape down the sides, drink the "dishwater" (or soup), then I wipe it out the remaining residue with about two squares of toilet paper and put that in my trash bag.
I usually hang my pot with my food bag overnight.

We always rinse out and drink.

Have always hung the pot with food in the food bag.
