Peel the pears, keeping the stem on for presentation. Cut a very thin slice off the bottom of each pear so it stands up well.
In a medium saucepan, bring the water, honey, ginger, and vanilla to a boil. Let the syrup simmer, uncovered, for 10 minutes. Add the pears and keep simmering until you can easily prick them with the tip of a knife, about 20 minutes. Drain, saving the cooking syrup to use in a smoothie or a cocktail, then let the pears cool completely.
Melt the Chocolats Favoris Hazelnut Praline Fondue according to the packaging instructions.
Set each pear on a small serving plate. Drizzle generously with Chocolats Favoris Hazelnut Praline Fondue, then sprinkle with chopped hazelnuts. Serve right away.
