Fondue - pronounced [fahn-DOO] Rules
“If a woman drops a cube of bread into the fondue, she has to kiss all the men; if a man drops the bread cube, he has to buy a bottle of wine. If the person drops a cube of bread for the second time, he or she must host the next fondue part,” according to Hamlyn Press, publishers of The Fondue Cookbook.
One of the most popular Fondue customs is if a lady loses her bread cube in the Fondue she owes the man to her right a kiss. If a man has such a mishap when dining in a restaurant, he should buy the next round of drinks. At home, he owes his hostess a kiss!
Fondue tradition states that if you drop the food off of the fork, and into the pot, you have to kiss the person next to you.
Another fun Fondue tradition is to leave a thin layer of Fondue at the bottom of the caquelon. By carefully adjusting the heat, this layer will form into a crust known as "la religieuse" - the religious one. Lift it out and distribute among your guests. It is considered a delicacy.
