Sai Krok Isan is a traditional Thai fermented sausage appetizer originating from the northeastern region of Thailand. The sausage is made from a mixture of ground pork, garlic, sticky rice, herbs, and spices, which is then stuffed into natural casings and fermented for a period of time to develop its unique flavor profile. Sai Krok Isan is typically grilled or pan-fried before serving, and it is enjoyed with fresh vegetables and chili dipping sauce.
