Pour in white wine to deglaze the pan, scraping up any brown bits. You'll know all of the
bits have released when you run your spoon over the bottom of the pan and it feels smooth. Bring to a boil over medium-high heat. Raw wine throws a sharp scent that pushes your face back. Step away a few seconds, then come in from the side. You'll know it's ready when that scent is gone and you smell fruit and shallot instead.
