noun
grated yam
Refers to a sticky, grated preparation of yam (often Japanese yam or nagaimo), commonly served over rice or with soba.
とろろをご飯にかけて食べるのが好きです。
I like eating grated yam over rice.
このそば屋のとろろそばは絶品だ。
The grated yam soba at this soba shop is exquisite.
The word is of Japanese origin, likely derived from the sound or texture of grated yam. The kanji 薯蕷 are Chinese-derived characters for yam, but the reading とろろ is an example of jukujikun (a native Japanese reading applied to a kanji compound).
