NopeLooks like dragonfruit to me.
I've seen this, is it the Thai fruit that stinks, name escapes me ATM.
Galangal?
This plant is used in Thai cooking (flower, stem, seed pod) but the root part isn't so much. The root is used much more in Chinese cooking.
It doesn't look to me like mara but it could be a type of melon?
Lotus Root?
I was eating lotus flower buds only this week in Vietnamese cookingThais use lotus stems; top right.
But personally, I've not seen the root used.
I thought you were joking but it looks like that's what it is! A new one for me.Long pepper?
Had to look that one up, but I think you're right as well.Long pepper?
