This is the first time I brought home the Japanese sweets called Kamome no Tamago (Seagull’s eggs). So I was very surprised to find how popular it is (see here, here, and here). Apparently the factory which makes this sweet was damaged in the Tohoku earthquake of 2011, but has clearly sprung back into production. I learnt that the chocolate and cake covering over the white bean paste was a revolutionary idea when it was first made, but the sweet is now a very common omiyage (travel souvenir).
I didn’t know that, but I’m happy. So is The Family, and so will my niece be, when she recovers enough from her flu to bite into this. If I have anything to complain about, it is that the white bean paste seems to be a little sweeter than the more common red bean paste.
