Thai farmers dumped a ton of mangosteens on the street in front of city hall to protest the low selling price. I’m pretty sure all the government workers rushed out to scoop up their share.
3 baht per kilo does sound pretty low, though. They retail for 18-20 baht/kilo up here in the northeast; the best quality ones at their peak went as high as 25 baht/kilo a couple months ago.
I do have to say that if you’ve never had a fresh mangosteen, you are missing out on one of life’s real pleasures.
