I'm not sure exactly what to call it, perhaps an
old wives' tale or a
popular misconception or perhaps even the cold hard
truth, but it is commonly believed in
Japan that eating eel during the summer will grant you increased
sex drive and
sexual stamina. For some reason this only works during
summer, which is why unagi is most popular then and many stores will have discounts on
unadon and the like.
I just like it for the
texture and the
taste. Really.
