Looking for a holiday cocktail that will help you escape it all? Try the Caribbean Christmas, suggests Editorial Director and resident Milk Street bartender J.M. Hirsch. It marries the richness of eggnog with the lighter, brighter flavors of a piña colada. It calls for coconut water, instead of heavy coconut cream; egg whites to produce a frothy texture, orange liqueur, cinnamon and plenty of rum. Happy holidays!
