We have always been averse to cocktail mixers. That said, we’ll always remember the first time we tried Bittermilk’s New Orleans Old Fashioned Rouge. It’s basically a complex simple syrup, featuring classic ingredients like wormwood, gentian root, and cochineal (red beetle). Pour 1/2 oz over rocks with 2 oz of your favorite Rye, stir, and garnish with a lemon twist for a damned-near-perfect Sazerac.
