If fresh-ground nutmeg is not an option, you can substitute 3/4 teaspoon of the already-ground version. But if time allows, go for the fresh ground. As someone who had never bothered to grate fresh nutmeg before, it was a revelation.
I think 1:1 is a good ratio of secret mix to rum, although if you like a stronger drink, you can adjust it to be as much as 1 part secret mix to 2 parts rum; 1 1/2 parts rum would probably be nice, too.
For the secret mix
Yield: 12 ounces, enough for eight drinks or one pitcher
- 8 ounces fresh-squeezed lime juice
- 1/2 cup granulated sugar (I like turbinado, or demerara)
- 1/2 ounce Angostura bitters
- Heaping 1/2 teaspoon of fresh-ground nutmeg (see Recipe Note)
For the Planter's Punch
Yield: 1 cocktail
- 1 1/2 ounce dark Jamaican rum
- 1 1/2 ounce "secret mix"
- Crushed ice
- Mint or cocktail cherry, for garnish
1 Make the secret mix: Stir the secret mix ingredients together until the sugar dissolves. Allow to steep in the refrigerator for at least 2 hours.
2 Make the punch: Add rum, ice, and secret mix to a shaker. Shake for about 20 seconds, and then pour everything into an old fashioned glass, or a comparable 6- to 8-ounce glass.
3 Garnish: Garnish with mint, or a cocktail cherry, or anything else that strikes your fancy.
To make a whole pitcher: Make the secret mix, then add all of it and an equal volume of rum (about a cup and a half, or 12 ounces) to a pitcher. Add 10-12 ice cubes and stir vigorously. Store in the fridge until you’re ready to drink, then serve over crushed ice.
