Ginger often doesn't come up all at once. Fortunately, you can keep a ginger root for a while. that's how you do it...
Do not put ginger loose in the refrigerator, but rather put it in kitchen roll wrapped in a ziplock bag † You can store ginger in the refrigerator for about three weeks. Or even better:use beeswax wrap. You can rinse them again and again with cold water and use them again. Better for the planet. This we quite like it.
Store ginger in the freezer. Whenever you need a piece, you can grate it off and use it right away. Ginger can be stored in the freezer for a few months.
Grate the ginger, place on baking paper and place in a cool and dry place. After about four days, the ginger is dried. Once the ginger has dried, you can keep it for about a year.
