I bought this tea cake at Uwajimaya, a massive Asian market in Seattle, in their tea aisle (not section, literally, a whole aisle). The cake is imported by a local company and comes in a sealed package and a rice paper wrapping. Opening it up, it smells delicious and hearty. In the cup, it’s even better. It’s earthy without being too overwhelming and isn’t astringent. Delightful as a light breakfast tea!
