haifagirl: I think it goes like this:
You need three conditions to return food to the fire:
– flame covered
– intention to return
– still holding onto pot.
The first condition must be fulfilled.
Only one of the other two is needed, bedieved.
I think what I learned about putting on the floor is that it is so obviously off the fire, that even if you do have the intention to return, you cannot do so.
