Have you ever wanted to make a stir-fry recipe that uses just “a few slices of ginger” but you passed it by because there was no ginger in the fridge? Then even if you do buy some ginger at the store, you know you’re buying 5-10 times the amount you need, only to watch it gradually shrivel in the produce drawer over the next few weeks.
I’m happy to tell you there is a solution to this ginger quandary. It’s easy to preserve fresh ginger. Purchase firm, fresh pieces of ginger, peel them and slice them crosswise into small medallions. Put these ginger slices in a lidded glass jar and add enough white wine or vinegar to completely cover the slices. Seal the jar and store in the refrigerator. Remove slices as needed for stir-fry or other Asian foods. The ginger will keep for several months when preserved this way.
