Fondue has rules
Cheese fondue (not chocolate — that's dessert fondue) is eaten in winter. Stir in a figure-8 pattern. If your bread falls in, you buy the next round of drinks. Pair with white wine or tea — never water (it causes the cheese to solidify in your stomach, or so they say).
Tip: Fondue is communal — groups of 4+ only. Eating fondue alone is sad even by Swiss standards.
