Well, the next day, I cut some lilac blossoms. I made a bouquet with some and transformed the rest into Lilac Sugar.
This is really more of a method than recipe.
First, I washed the blossoms and let them dry completely. Then I pulled the flowers from two full blooms and made sure there were no stems.
Next, I poured granulated sugar into a dry, quart sized container and mixed the blossoms in. I sealed it and put it in the cabinet. In a few weeks, I'll try making lilac sugar cookies, Lilac brioche, or maybe even lilac whipped coconut cream...
