One evening, we were walking to the laundromat, and the aroma from a neighbor’s orange tree was so arresting that we found ourselves sniffing for the good part of an hour. The perfume was extraordinary. We tried distilling the fruit, but the acids in the juice were unstable, so we thought: let’s use the flowers. Since we only pick at the height of bloom, we’re constantly battling time and the elements. The complex, floral aroma is always worth the trouble though, and much more.
