Prepare Massaman syrup: toast 1 tablespoon ground mace, 5 cinnamon sticks, 2 tablespoons coriander, 6 cardamom pods, 15 cloves and 2 nutmegs over low heat for a few minutes. Add 2 cups dark brown sugar and 2 cups water, bring to a boil, turn off the heat and steep at least 2 hours, then strain. Measure the listed 25 cc portion.

Stir the rye, sweet vermouth and prepared syrup with ice for 30 seconds or until well chilled. Strain into a lowball glass and top with 4 dashes aromatic bitters, following the source method. Garnish with a coin-sized piece of orange rind.
