He found this drink on an Instagram site call @aboutdrinksandbars sun by a group called the Cocktail Society. I checked them out and they have a website full of cocktail recipes at www.cocktail-society.com. He noted he had made this drink and as he didn't have prosecco, just used simple syrup and it was still great. As my friend was coming from Toronto, I put it on my list of must makes.
I didn't want to open a whole bottle of more expensive prosecco to make the syrup so bought one of those single serving bottles of dry sparkling wine instead. I have included their photo as it's amazing presentation. Looks like they float a dried orange slice in each. I had picked a bag up at Modern Bartenders a month ago, so was ready to go. And for anyone who doesn't know, the egg white is what makes that great foam on top.
