for New Year's Eve we often have fondues
you can have oil, chocolate, cheese, &/or broth fondues
Have a variety of items and a few different cooking methods
How many people are planning on having over?
It is nice to have lots of fondue pots (borrow from friends) so they do not get too crowed and lose heat
I have made bagna caoda
before which is oil and anchovies and garlic fondue (Italian version). It sounds like a strange combo but it is great.
