I used two types of preserved melon. The black one from a can is slightly salty! The yellow one, bought from the market, is homemade by the vendor and has a sweet-salty taste. It's delicious for steaming fish or stir-frying with minced pork! Generally, this type of long fish doesn't fit in a rice cooker, so you need to cut it in half or use a frying pan to steam it. Using a steam oven is very convenient, as it can fit the whole fish!
