Uni -
n., Japanese
Writing
It has three different spellings in
kanji. One form means
sea chestnut, which comes from its appearance. It is also often spelled out in
hiragana. Japanese scientists like to use
katakana to spell living things in general.
Definition1
(1)
sea urchin, or (2) salted sea urchin
roe (meaning the eggs) that is used for food. (Sorry to disagree,
sensei.)
There are many kinds of uni, of various colors and sizes.
As a sushi item
Best eaten salted, uncooked, and still juicy. Uni is indeed a delicacy, and as it is often the case with the more popular
sushi items, it is higher in calories and higher in price. Uni is served either as
neri uni (egg paste) or
tsubu uni (with the eggs still having form), and it is in season during Spring.
A common misunderstanding
A common misunderstanding held among Americans, told to gross out other Americans, is that uni is the semen part. Actually, only the eggs of sea urchins are food. They are most likely confusing uni with shirako, which comes from a different fish.

2009-02-25: Update and a correction: According to a TV show on uni, apparently it's
both the eggs and the semen that are eaten in Japanese cuisine. You either get egg packs or semen packs from a single sea urchin. Surprisingly, they both look and taste very similar, and are sometimes not distinguished at food markets.
