Two Tuesdays ago, I dusted off my copy of the Experimental Cocktail Club Cocktail Book and found my list of drinks left to try. The list item that called out to me was the Vieux Rectangle invented by Arthur Combe at the E.C.C. Paris Curio Parlour as his twist on a Vieux Carré. In the glass, the Vieux Rectangle gave forth lemon and anise aromas that preceded a grape-driven sip. Finally, the brandy began the swallow followed by orange, anise, and clove notes.
