noun
deep-fried bean curd; undercooked
Primarily refers to a type of thick, deep-fried tofu (similar to 厚揚げ). The 'undercooked' meaning is a rare, literal reading of the kanji and is not the usual sense.
生揚げを煮物に使うと、味がよくしみます。
When you use deep-fried bean curd in simmered dishes, it absorbs the flavor well.
この生揚げはまだ中が生っぽい。
This deep-fried bean curd is still a bit undercooked inside.
Compound of 生 (nama, 'raw') and 揚げ (age, 'fried'). The name likely refers to the fact that it is fried only once, leaving the inside soft and 'raw'-like, or to its use before further cooking.
