Here's a little number that will cause a tremendous stomach ache: Foi Thong (Golden Threads), Thong Yip (Golden Egg Drop), and Thong Yod (Golden Egg cake). Egg yolks cooked in boiling syrup. The ants will love it.
It's a specialty of Phetchaburi. While I was there I ate too many. I have no photographic evidence as after taking one bite, I was a mess, and in no state to operate a camera. This one here I quickly snatched up yesterday against my better judgement.
