A reader wrote in recently asking me about how to handle cakes that have been traditionally stored. The cake has obviously been through some traditional storage, as you can see here
First of all, it’s useful to get a sense from looking and smelling the cake to see how heavy the storage was – how wet, for how long, basically. There are some hints. You can smell it. You can observe the amount of mold on the surface, although that’s not a good indicator because some people actually use brushes to brush off most of the spores. You can also open the cake up a bit to see what it looks like inside – if it’s really white inside or not. Really heavily stored cakes also often have some warping – they get so wet that they warp under pressure of all the other cakes on top and sometimes around them. This doesn’t look too bad.
The reader actually had two questions – will this cake contaminate the other cakes he owns, and how to deal with this – to make it get better, I suppose?
The first thing to note is that since mold can grow on anything, just putting your moldy cake in the same storage space as your other cakes is not automatically going to cause mold on other cakes, unless your storage environment allows it to happen (wet, basically). At 30% RH, that’s not going to happen to this reader’s storage situation. It could, however, impart a bit of a smell to the other cakes in the same container, so my advice was to put it separately, perhaps in something like an unsealed cardboard box, and just forget about it. This comes to the second point – often times the biggest problem with these traditionally stored teas, especially if they haven’t been out of their wet storage phase for too long, is that all you can taste is the musty, damp forest floor smell. The rich flavours that you can get from traditionally stored teas aren’t apparent yet, especially the sweeter flavours. To get rid of the sometimes pungent smell, the best way to deal with it is to just let it air out a bit. This is the one time when you do want a bit of airflow or at least air exchange. It takes time, but eventually the really obvious musty smell will go away and you will have something that’s more drinkable. These are probably drinkable now, but it should get better with age.
I also have friends who would brush off the spores themselves, although for your sanity and health I’d do that outdoors. Get a new toothbrush and just lightly brush them off. It really won’t change much of anything but it might look better, and to some people that’s actually an important psychological step in dealing with the tea, it seems.
When drinking traditionally stored teas, it’s often not a bad idea to throw away the first two steeps. A good old friend of mine who grew up drinking these often said the real taste doesn’t start to show up until about steep five. There’s a certain truth to that – everything before is really the storage talking. Definitely rinse the tea, probably twice, before trying it. If it’s still super pungent, you might want to let it sit some more, or throw away another infusion. Part of the fun is learning how they transform, and traditionally stored teas change in ways that are more obvious than naturally stored teas.
Finally, I should add that one of the most interesting things you can do is to try to find traditionally stored cooked puerh – they are actually quite different, and richer, than naturally stored ones, which tend to be rather boring. The traditional storage process also tend to get rid of the nasty, pondy taste. They also come cheaper. I’m not sure if any vendor out there is selling something like this, but if not, they should look for it because I think there’s a market for this stuff.
