I just flatten the hash onto cardboard. The cardboard acts as a desiccant and pulls the water out. Flip the patties once. comes out plenty dry. i stopped freezing it just saw no need.
So what's the consensus on drying the ice water extract (bubble hash?)?
Some say into the freeze and out to thaw and this process is repeated many times. Others put it on cardboard and dry it that way before freezing.
