Fresh ginger is great, but it’s something I don’t use all the time and it usually goes bad or dries out by the time I want to use it again. Since I almost always use it in cooked food, I’ve found a good way to preserve it.
Just peel and cut up the ginger, put it in a tupperware and cover it with vodka. It will keep in the fridge forever. When you cook it the alcohol burns off so you can’t tell the difference and you also get some ginger infused vodka out of it that you can use for cooking or for drinking:-)
