This is really simple! The sliced pork cooks through quickly, so it is done in no time at all! It tastes great cold or warm.
I made my husband'a favorite mayo-ponzu on a hot day when we have no appetite.
Scum will rise to the surface, so make sure to skim it off. If you have reservations about boiling the pork and shimeji mushrooms together, then boil them separately, and add together afterwards.
