Recipe: Crystallized Ginger. Spicy and sweet, crystallized ginger can add a wonderful zing to cookies, cakes, ice cream, and cranberry sauce. We also like it finely chopped and sprinkled over savory dishes like roasted acorn squash and pumpkin soup. Chewing on the ginger treat can even help soothe an upset stomach. Although a jar of it can be outrageously expensive at the store, crystallized (or candied) ginger is quite simple to make at home.
