Som Tum, also known as Green Papaya Salad, is a refreshing and spicy salad that is a favorite among locals in Bangkok. It is made with shredded green papaya, tomatoes, green beans, peanuts, and chili peppers. The salad is dressed with a tangy and spicy dressing made from lime juice, fish sauce, and palm sugar. Som Tum is a perfect balance of flavors, with the sweetness of the papaya, the sourness of the lime, and the spiciness of the chili peppers.
