This signature drink mixes autumn pears and fresh raspberries with a splash of vodka.
Puree raspberries and sugar in a food processor; strain into a bowl. Refrigerate until ready to use (up to 2 days; makes enough for 60 drinks). Pour nectar, Chambord, and vodka into a cocktail shaker filled with ice; shake to combine. Strain into 2 martini glasses. Pour 1/2 teaspoon raspberry puree into each glass.
