Infusions
Combine the rum and milk in a container and measure the weight of the liquid. Calculate 0.2% of the weight (multiply by 0.002) to get X grams. Let the mixture rest for 5 minutes, then stir in the Citric Acid Solution. Refrigerate for at least 12 hours. Stir in X grams of Pectinex, then cover and let sit for 15 minutes. Divide the liquid among your centrifuge containers. Weigh the filled containers and adjust the liquid in each to ensure their weights are exactly the same; this is important for keeping the machine in balance. Run the centrifuge at 4,500 rpm for 12 minutes. Remove the containers and strain the infusion through a paper coffee filter or Superbag, being careful not to disturb the solids on the bottom of the containers. If any particles remain in the infusion, strain it again. Funnel back into the rum bottle and refrigerate until ready to use, up to 2 months.
