Bamboo shoots, whether in soup or stir-fried, are a familiar and beloved dish in Vietnamese cuisine. Bamboo shoots are versatile and can be cooked in many delicious ways. However, they often contain preservatives and fresh bamboo shoots, if not properly prepared, can be bitter and harmful to your health due to their natural toxins. Before cooking bamboo shoots, follow these steps to ensure they are free of chemicals and bitterness.
Boil bamboo shoots with chili peppers and rice water
A simple trick to remove toxins from fresh bamboo shoots is to use rice water. You don’t need to peel the outer layer; simply cut the shoots into manageable sizes and place them neatly in a pot. Cover the bamboo shoots with rice water and add a few de-seeded chili peppers. Boil until the bamboo shoots are soft, then turn off the heat. Drain the water and rinse the shoots several times with clean water. This method eliminates bitterness and removes toxins. Boiling the bamboo shoots before cooking helps to release the bitter resin and reduce the amount of preservatives.
Alternatively, you can cut the bamboo shoots into small pieces and boil them with a handful of Rau ngót (a type of Vietnamese herb). Once the water boils, drain it, remove the herb, and rinse the bamboo shoots. They are now ready to be cooked into a delicious dish.
Boil fresh bamboo shoots multiple times
This method is commonly used and similar to the previous one. Peel the outer layer of the bamboo shoots and place them in a pot. Boil them at least three times, then soak them in rice water for two days, changing the water twice daily to prevent sourness and maintain flavor.
Secret to removing toxins from fresh bamboo shoots using limewater
Soak the cut bamboo shoots in limewater for about three hours, then boil them multiple times. Continue boiling until the water turns clear, and always keep the lid off during this process. This ensures that the toxins are released as steam.
