Basashi (馬刺し, lit. "sliced horse")
is frozen raw horse meat, sliced very thinly and served on a
bed of ice, usually with some daikon shavings and a heavy
dollop of garlic paste on the side. If you like sashimi and
can overcome your prejudices, you will find that good basashi
tastes as smooth and creamy as the best tuna belly.
However, if the dish thaws too much, the tasty morsels will
degenerate into
stringy red strips that taste way too much like, well,
raw horse meat.
