She always knows what to try and what a place is known for. For instance Thais going to Chaiya invariably bring salted duck eggs, for which Chaiya is known, home to share. If they go to Petchburi they might come back with a type of fruit known as chumpoo. People going to Nakhon Pathom often buy pomelo, a citrus fruit in some ways similar to grapefruit. If they go to Ranong, they are likely to try a type of pork bun for which Ranong is known.
Every region has something different to try.
As usual, this year some of the best excursions were trips to markets. I think of markets as the real heart of Thai culture. I inevitably wish I had access to a kitchen because it is so inviting and fresh. In fact, it is hard to find a block in a Thai neighborhood that is very far from good food. We stay at Kasma's parent's house in Bangkok.
