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.
In a double old fashioned glass pour, in order, over a large ice cube. Garnish with a long, thin slice of Persian cucumber and a grapefruit peel.
