Truffle vs bonbon

A truffle is a rolled ganache, a bonbon is a moulded shell with a filling — and 'praline' means three different things in three different countries.

Why these get confused

Both are small filled chocolates sold in the same box. The construction differs, and 'praline' sits across both — in Belgium it means a bonbon, in France a nut paste used as a filling, and in the American South a sugar-and-pecan sweet with no chocolate in it.

Side by side

 TruffleBonbonWhy it matters
How it is madeA ganache set firm, then rolled or cut and coated.A thin shell cast in a mould, filled, then capped.The base gives it away: a bonbon's is flat and sharp; a truffle's is not.
AppearanceIrregular, traditionally dusted in cocoa — named for its resemblance to the fungus.Sharply defined and glossy, often with coloured cocoa butter decoration.
DifficultyForgiving. Rolling in cocoa hides a great deal, and only the ratio really has to be right.Demanding. Everything depends on tempering — a shell that will not release was not in temper.
Shelf lifeDays to a couple of weeks refrigerated, because a cream ganache is perishable.Set by the filling. A caramel or nut paste keeps far longer than a cream ganache.Relevant when buying either as a gift that will not be eaten immediately.

Choose Truffle when

Making filled chocolates at home for the first time, where a forgiving finish matters more than a sharp one.

Choose Bonbon when

When you want a thin snap of shell against a soft centre, and when the appearance is part of the point.
