1. Shrimp mushrooms need to be cooked for 15-20 minutes before they are cooked. Shrimp mushrooms are Pipi shrimps.

2. Usually put cold water into the pot and cook it on low heat for 15-20 minutes. It takes 8-10 minutes to cook on medium heat. If you use a pressure cooker, it can be done in 2-3 minutes. Do not add too much water when cooking Pipi shrimps, otherwise it will easily cause the taste of Pipi shrimps to become bland, thus affecting the taste of Pipi shrimps.
