These are normal eggs hard boiled in naturally hot sulphuric water bubbling out of the side of the mountains in Hakone. Once the black shell is removed, they look and taste relatively normal but I did feel a little queasy after having two of them.
Yes. That's right. On this plate were baby squid, horse mackerel and flounder. They were partly digested, having come from the inside of the stomach of an anglerfish. This must be the strangest dish on this website so far. Quite salty but pretty good.
