Place decarbed Mango Kush in the canister of the whipping siphon along with the alcohol. Screw top on tightly and charge with the first co2 cartridge, rapidly shaking for about 30 seconds after. Repeat with the second charge.
On the stove top, heat a pot of water to 200F and submerge the base of the siphon in the water bath. Allow 30 minutes of infusion in the water bath, shaking rapidly for 5 seconds every 10 minutes or so.
Remove siphon from the bath and place in the freezer (on the lowest setting) for 48 hours- shaking every few hours as possible.
After the two days, allow the siphon to come to room temperature and slowly release the CO2 gas to allow the pressure to escape.
Remove lid and strain tincture through cheese cloth into a mason jar and wring out as much liquid as possible. Store in freezer.
