Chocolate truffles are the end-of-meal treat of the holidays: a ball of ganache that melts on the tongue, in a slightly bitter cocoa coat. You make them the day before, they keep for a week, and in a pretty box they're the best-loved homemade gift.
It all comes down to the ganache: good dark chocolate, full-fat cream, and stirring from the center outwards to get a smooth, glossy emulsion, like a mayonnaise. The butter goes in afterwards, once the ganache is warm, for a melting texture. No professional equipment needed, just a little patience while it chills.
