Classic Negroni

Gin, Campari, sweet vermouth, in equal parts. The familiar story starts in Florence, with an Americano made stronger by replacing soda with gin. The exact history is not perfectly tidy, but the shape is what matters: soda out, gin in, and the drink pulls tight into three equal parts. Everything else here is this one with a single thing moved, so it's the place to start. It reads simple and punishes weak ingredients: a tired vermouth turns it harsh, a rich one turns it plush, and the gin sets how dry it sits.
