Are you sure they were not calling for a "Grease Pot"? <img src="/forums/images/graemlins/grin.gif" alt="" /> That would be a lightweight pot found in Walmart and K-Mart.

As for carrying butter that is quite easy - you just clarify it! Then it is shelf stable for about a year. Otherwise known as Ghee. I have a couple ways to do it on my website as well, if you are interested, I can post one or two here.
