Tips:
1. Boil winter bamboo shoots for 5 minutes in advance. It removes the bitter taste.
2. Add more cooking oil to stir-fry winter bamboo shoots because it can soak a lot of oil. Stir-frying it in enough oil is more delicious.
3. It is easy to overcook the abalones, so add it before simmering. With 5 minutes simmering, it has enough time to spread abalones taste over the dish.
