One of my colleagues visits China regularly and was given this tea as a gift. However they didn’t see themselves making the most of it so offered it to me.

I have no idea what to do with it though. It’s like a circular brick of compressed tea leaves. Do I just take off a chunk and leave it in hot water? Does the temperature matter, and do I need any particular tools?

I’ve only ever used tea bags so I’m a bit lost

Edit: also the expiry says November 2023… but it’s just tea right?
