How can I keep hot food hot when transporting it? +1 for the last paragraph's suggestions. The portables can be great, and our crock pot is stable enough to sit on the floor for short trips even without clamps (I won't attempt it for long trips).
Should I let stock cool with the bones/veg still in it? My goal mostly was to augment the great answer provided by Darin Sehnert with the suggestion that handling just the veg would run into slightly different considerations.
