The proper method is to spear the bread on the fondue fork from the white side all the way through the crust. This way, it is almost impossible to loose your bread in the fondue.
Then dip the bread in the fondue, in a decisive manner, stirring a little bit, without scrapping the bottom in order to wet the bread on all its faces and to stir the fondue at the same time.
Remove the fork from the fondue, let drip for a second or two over the pot.
Now slowly twirling the fork (so that the cheese does not drip all over), bring it back to your plate, and eat as soon as the cheese is at the proper temperature (1 or 2 seconds).
Traditionnal cheese fondue forks have a round handle, long enough so as to facilitate this rotation of the fork.
