This happened to me yesterday, and the inspirational culprit was none other than a Pluot.
The Flavor Queen variety of Pluots
Technically, it's a hybrid of a plum and an apricot, but it's much more plum-like in flavor and the Flavor Queen variety is sharply verdant in smell and taste at the outset. In short, it's utterly exhilarating. It reminds me of something Kedra Hart of Opus Oils could do something really fun and interesting with in a perfume blend. I can imagine essence of yellow Pluot married to mimosa or fleur d'oranger, some earthy jasmine sambac, a dry wood base and a touch of musk.
What about you, are there any scents you've encountered in your day-to-day life that have made you think of how incredible they would be in a perfume? Dish.
