The heating time of volcanic sausage in microwave oven depends on whether it is thawed in advance. If it is not thawed in advance, it needs to be heated for 2 to 3 minutes before eating. If it has been thawed, the heating time is generally about 30 seconds, and it cannot be heated for too long, otherwise the volcanic sausage will be baked until the casing bursts, the surface is dry and the taste is greatly reduced.
