- Step One
Lightly toast 1/4 cup whole dried allspice berries just until fragrant then crush to break up, but not completely turn to powder. In an airtight container, combine the allspice with 1 1/8 cups 151 demerara rum (Lemon Hart). Let steep 10 days in a cool, dark place.
- Step Two
After 10 days, strain the infused rum through cheesecloth, then a coffee filter, to remove allspice. In a saucepan over medium-low heat, combine 1 1/2 cups water with 2 1/2 cups brown sugar. Stir to blend until sugar is completely dissolved. Let brown sugar syrup cool, then add the infused rum. Funnel into an airtight glass bottle or jar and let sit 30 days in the refrigerator. This will level out the heat of the allspice. Keep refrigerated. Will last about six months.
