I had this again yesterday, and I enjoyed it so much!
I used boiling water to pre-heat the kyusu (but only 150 for 1 min 45 seconds for the brew). Anyway, before I poured the water over the leaves, I smelled them, as they had been sitting in the warm pot for a few moments.
I was knocked back by an aroma as if I walked into a bakery, or just pulled fresh muffins out of the oven! How can a green tea smell bakey? Well it did, and deliciously so.
