Named for New Orleans' mayor Count Louis Phillippe Joseph de Roffignac (1820-1828), who beautified the city with cobblestone streets, gas lamps and a massive landscaping plan. This particular recipe is inspired by the mad chemists behind the bar of the Bourbon O Bar in New Orleans, Louisiana.

0.25 oz. Apple Cider Vinegar
Build in a highball glass full of ice. Start with cognac, then raspberry liqueur, apple cider vinegar. Fill rest of glass with soda water. Serve with straw (or other stirring device). Garnish with raspberries.
