Once while making this concoction I ran out of Cognac. I was already filling up my shaker, so there was no way back. After careful observation of my bar inventory I selected a bottle of apricot brandy as the most close relative. The resulting version used 30 ml of Cognac and 20 ml of the apricot brandy. This invention out of necessity felt so good — like a boozy nectar! — that I use this slightly tweaked version of the famous cocktail ever since.
