First remove the zest from the limes and then place them in a mason jar. Squeeze the juice of the limes and save.
Now peel and dice the ginger and put it in the jar along with the cloves, star anise and the almonds previously roasted in a pan. Now add the overproof and the white rum and let it steep for two days in a cool, dark place, shaking vigorously once a day.
After the steeping time, strain the rum and fill up with the sugar syrup, lime juice and almond syrup. Pour everything into a bottle.
