And much like the landscape changes as you move around the country, the food changes too. Down in Southern Thailand, especially around the islands and coastal areas, you are going to find loads of fish, seafood and ingredients shaped by the sea. As you keep going further south, you also start to notice stronger Muslim influences in the food, which gives that part of Thailand its own identity again. Then up in Isaan in the northeast, things get a lot bolder. This is where your som tam comes from and where the food can be seriously spicy, punchy and packed with herbs. If someone has ever told you Thai food nearly blew their head off, then there is a fair chance they ate something from Isaan without realising it. Then up in Northern Thailand, the food changes again. You get dishes shaped by old Lanna traditions and nearby influences, and this is where you find khao soi, which loads of people call a noodle soup but is really much closer to a curry, and sai ua, which is one of my personal favourites. A proper herby, spiced grilled sausage. Then in Central Thailand, you get this brilliant mix of everything. Internationally recognised dishes, regional dishes, local spots, busy food scenes, and basically anything you could ever want.
