The co-creator of this app is one Brandon Herring. When I saw his name, I thought it begged for a eponymous signature cocktail. And I thought it would be extra-hilarious not to make it with Cherry Heering. So funny. Here you go, buddy. (He already whipped up his own version, hence "No. 2").
1 oz Schladerer kirschwasser
1 oz Cocchi sweet vermouth
1/2 oz Mathilde poire liqueur
2 dashes Fee Brothers cherry bitters
1 oz prosecco
Stir the first four ingredients and strain into a chilled cocktail glass. Top with the prosecco.
