Is that like fondue?
Kall bought me a fondue set for my birthday. The first time we used it we put heaps of different types of cheeses in it, so all the cheese was all yummy and melted and we dipped bits of bread and other stuff into it ....
Then we put chocolate in it and dipped pieces of banana and dried apricot ... that was very good too.
You can put hot oil in it to cook meat as well. Looks like I might have to get another couple so I can do the hot oil, cheese and chocolate all at once!
