Ginger at hand throughout the year

Lately, I find fresh food more and more often ginger at extremely reasonable prices. Since I always use ginger as a small cube, I once took the time to peel a quantity of about 10 ginger rhizomes, cut into smaller pieces, then into slices and strips and finally into fine cubes - and that with one extremely sharp knife, so that nothing is squeezed.

The cube I deep-frozen in a plastic box with lid. So I can, if necessary, the desired ginger frozen directly into the wok or similar. give, no longer has to do Schnippelarbeit more and have it quickly at hand.
