Much like calling lily of the valley "muguet", indulging in unnecessary French and calling blackcurrant "cassis" makes the plant in question sound ever so much more mysterious and interesting.
Wait, no. "Cassis" sounds cool, but "muguet" just sounds kinda goofy when you stick it in the middle of a bunch of English. There's a graduate thesis in that.
Anyhow, no matter what you call it, blackcurrant is a glorious aroma that hovers at the meeting point of dark fruit and green, resinous twig, and it's conveyed beautifully by the Coeur de Cassis candle ($16) from Voluspa. Plus, the tin is gorgeous and will not resemble a jumbo peanut butter container once it's empty the way that those glass candle jars will.
