noun
tilefish; horsehead tilefish
A marine fish prized for its sweet, delicate flavor. Often used in high-end Japanese cuisine, especially as grilled or simmered dishes.
アマダイの塩焼きは絶品だ。
Salt-grilled tilefish is exquisite.
市場で新鮮なアマダイを買った。
I bought fresh tilefish at the market.
鯛 (sea bream) is a different fish; アマダイ is not a true sea bream despite the kanji 鯛 appearing in its name.
The name アマダイ (甘鯛) literally means 'sweet sea bream', referring to its mild, sweet taste. The exact origin of the name is uncertain, but it is not a true sea bream (鯛).
