This rich sour was built around the flavor of Saigon cinnamon, which is more potently aromatic (think Red Hots) than your standard Ceylon cinnamon. The base of the drink is split between blended scotch (look for something lightly peated, like Black Grouse or Monkey Shoulder) and brandy, then balanced with lemon juice, tart grenadine, egg white, and a finishing dust of cinnamon. It has all the hallmarks of a holiday-appropriate sour.
