I’ve been looking for 'yama-imo 山芋' which is kind of 'Yam (potato)' for a long long time in Perth.
'yama-imo' have very sticky texture when grated and are used for Okonomiyaki, soba noodle, rice topping, sashimi etc etc. Not a daily used vegetable, but common in Japan.
I found odd looking veggie labelled 'Yam Yam'...
looked different from the one I'm after, but bought it anyway just to try.
Very expensive, $17 KG ！
I bought only one small piece, costed $4 😣
1 piece of yam, size of a potato, $4....
Peeled and grated.
It didn't have sticky texture after grating at all, a bit watery like grated Japanese radish(daikon).
It was very tasty ! ! It had nice sweet flavour 😋
I'd love to try make new dish using this 'yam yam' if it's a lot cheaper 😓
