Back in 2007, Jacob Briars introduced this cheeky homage to the Corpse Reviver No. 2 with blue curaçao instead of Cointreau. “It tastes broadly and very much like a classic cocktail from the 1920s and ’30s—it just happens to be blue,” Briars says. He usually reaches for a blue bottle of Bombay Sapphire gin to seal the deal.
