Negroni Sbagliato Bianco or White Mistaken Negroni

As Marion and Michael had just released the book Public Natures, relating architecture to landscape, and had recently completed the redo of the Brooklyn Botanic Garden buildings, I wanted something referencing green. Michael grew up in Italy and loved the Negroni, while Marion cleaves almost uniquely to prosecco. That led naturally to a Negroni Sbagliato, clarified and with one tiny aromatic embellishment from cucumber.
