Before blanching, bamboo shoots need to be blanched in boiling water for 2-3 minutes, and then immediately soaked in cold water. The advantage of this is that it can soften the fiber of bamboo shoots and reduce the bitterness. At the same time, cold water can help bamboo shoots cool down quickly and avoid nutrient loss caused by high temperature treatment.
Put the processed bamboo shoots into the pot and add enough water, which is enough to drown the bamboo shoots. Put the pot on the fire, bring the water to a boil and simmer for 5-8 minutes. The blanching time should not be too long, otherwise the bamboo shoots will be soft and rotten or lose their taste. If the blanching time is too short, the bitterness cannot be removed.
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 bitter taste or other bad taste, or a little bitter taste, and can only be eaten after processing to remove the bitter taste.
How to choose bamboo shoots:
1. Look at the shape: when choosing bamboo shoots, choose the one with the same thickness at the head and tail, so that the bamboo shoots taste more tender.
2, look at the size: don't buy too big bamboo shoots. It is best not to exceed 30cm from the root to the top. If the bamboo shoots are too big, the root fibers will thicken and age. When cooking, the roots of bamboo shoots have to be cut off a lot before they can be used, and the taste of bamboo shoots is not good.
3. Look at the length of the node: bamboo shoots grow on the node. When buying bamboo shoots, you should look at the distance between nodes. The closer the distance, the more delicate the meat will be.
4, look at bamboo shoots: peel bamboo shoots, look at bamboo shoots. The whiter the bamboo shoots, the crisper they taste. Don't choose green, bamboo shoots taste very astringent.
5, look at the skin color: when the bamboo shoots are buried underground, the color is bright yellow, and will gradually turn blue when they grow up. Therefore, when purchasing bamboo shoots, you should choose bamboo shoots with bright yellow skin color.
