Stir all ingredients gently with ice for 10-15 seconds. Strain into an old fashioned glass with a large ice cube, and garnish with a lemon cheek.
Mace and nutmeg syrup
Toast spices in a medium saucepan until you can smell them, about 2 minutes.
Remove from heat and crush them with a mortar and pestle.
Meanwhile, in a saucepan over medium heat, bring the sugar and water to a low simmer. Add the toasted mace and nutmeg, and remove from heat.
Allow to steep for 12 hours at room temperature. Strain the spices out, and bottle in a clean, sanitized container for 7 to 10 days in the refrigerator.
