The roots are scaled and cleaned with a steel wool scrubber and blended with vinegar to the desired texture, and stored in small jars. I used 250 ml jars, but it is probably better stored in 125ml jars, since oxidization occurs everytime a jar is opened, and the colour changes from the pristine white to a dull white over time. Total time 4 hours. There is still a few 125 ml jars from 2007, and it is still in pristine condition.
