Nagaimo (長芋) is a mountain yam (山芋 ) native to China and is grown across East and Southeast Asia. It has a long and slender body with light yellow skin, white hairy roots, and white flesh.
It can be eaten raw, unlike other types of yams and potatoes, and is great cooked, steamed, or stir-fried, and it’s best known for its gooey and slimy texture when grated. When grated raw, it has a unique sliminess that’s easy to digest and is great with rice and soba noodles.
We fell in love with these during our recent trip to Japan and were pleasantly surprised that they grew so well in Singapore!
