Here’s a fast way to infuse booze with flavors — cacao nibs, herbs, etc — using nitrous oxide and a whipped-cream maker:
Put room-temperature booze into the cream whipper. Add herbs, seeds, whatever. Close the whipper and charge it with nitrous oxide (N2O -the regular whipped cream chargers). Swirl gently 30 seconds and let stand 30 seconds more. Quickly vent the N2O out of the whipper, open it, and strain out the infusion. Done.
