| Re: Group Buy: Popcorn Machines, Supplies and Accessories It's a place where popcorn seats before you take it out of the popper - bottom of it. Most poppers have the warming tray, but the economy ones don't . If you make a batch of popcorn and take it out of the popper right away, you do not need the warming tray, but i in the popper which has a warming tray if you did several batches, you can leave the popcorn there, they tray will keep it warm. |
