Nishime is slowly stewed down root vegetables. It is a traditional Japanese food. Often prepared as one of the New Year’s celebration food, but can be eaten other occasion, particularly when many people gather together.
If it is difficult to get all those vegetables in the U.S., you can use only available vegetables. The point of nishime is to cook slowly to let the vegetables absorb the flavor while keeping the shapes of vegetables intact.
This recipe is more involved than it appears, as each vegetable has to be prepared individually before stewing together. However, the final result is satisfying, and it keeps in a fridge about a week. Great for vegetarians.
