I tried using the acid/hot wat

I tried using the acid/hot water/freezing to get the red bloom but it didn't do anything with the old leaves.

I think the pressure cooker squeezed everything out of them.

My next attempt will be to use the fresh dry tea leaves. I'll also have to try using the grinder to break it down to a finer powder.

lol I like all the experimentation. :)
Yup, me too! Right up my alley!
The fun part of experimenting is the discovery of something new. Right now, my favorite is using the chilled tea that I made in the pressure cooker. I add a little local honey to it, stir and then drink.
