2. Bamboo shoots are perennial evergreen plants of Bambusoideae, which are native to China. Bamboo shoots are the ingredients of Jiangnan cuisine. In the past, there was even a saying that "you can't eat bamboo shoots without bamboo". Although all bamboo shoots are produced, not all bamboo shoots can be called cooking products. As a vegetable bamboo shoot, it must have tender tissue, no bitterness, no other bad taste or slight bitterness, and can only be eaten after being processed and debittered. So bamboo shoots are inherently bitter. Usually, sweet bamboo shoots are bought and sold in big supermarkets, and some vendors often sell bitter bamboo shoots as sweet bamboo shoots. Because it's hard to tell, people who don't understand are easily fooled. But actually, bitter bamboo shoots are edible.
