When I was growing up, I was weirded out by chocolate-covered strawberries. I did not understand why anyone in their right might would combine fruit with chocolate.
I've sinced acquired a taste for such flavor marriages... sort of. I'm still grossed out by certain sweet-and-savory combinations. I only just started liking chocolate-covered pretzels.
And there are apparently a number of scent combinations that a lot of people like but that I just find arbitrary and objectionable.
Like this product, for example--One With Natural Dead Sea Mineral Bath Salts in Lavender Tangerine:
I really don't understand the combination of lavender and tangerine. I'm repulsed by anything lavender-scented to begin with, but regardless of that, tangerine doesn't strike me as a good companion for it.
I mean, if someone came up to me as said, "Here, sniff my new blueberry-and-latex-glove-scented candle," I'd say, "OK, sure, that makes more sense than lavender and tangerine."
So how about you? QQ: What fragrance combination do you just not understand?
