You can sprout your own kongnamul at home, and they are tastier and nuttier than the ones you buy in the store.
1 cup of dried soybeans will make 1½ pounds of sprouts. When the beans
are sprouted, more vitamins and minerals are created, making them even
more healthy than the original beans. And homegrown kongnamul have wonderful, long roots, unlike kongnamul sold in grocery stores.
