     Bamboo is a giant grass that grows in warm places. It has many uses. Everything-from chairs and

fishing rods to basket and paper can be made from it. And that's not all. It can be eaten, too. People in

China like bamboo shoots very much. They think the bamboo shoots are a delicious vegetable for parties

and meals.

     In many parts of Asia, bamboo shoots are a favorite food. The winter shoots are the best because

they are soft, with a white and green color. Usually they are boiled in water with some salt. Spring shoots

are darker and harder, so they take longer to cook. But they are cheaper than winter shoots.

     Fresh bamboo shoots are seldom found outside bamboos' hometown. But people in other places can

buy bamboo shoots, too. These shoots are kept in bottles and cans. They need no cooking and are almost

as good as fresh bamboo shoots.
