When it comes to street food in Thailand, Isaan sausages are a standout favorite of mine. Whether you’re in Bangkok or the northeastern provinces, these sausages are a convenient and delicious snack that’s easy to enjoy on the go. The distinct flavors and unique preparation methods of Isaan sausages make them an unforgettable part of Thai cuisine. While the basic ingredients are similar, there are many regional variations that make each version worth trying.

What Exactly is an Isaan Sausage?

Isaan sausages, known as Saigrok Isaan in Thai, are typically made from fermented pork, garlic, and sticky rice. The fermentation process imparts a sour taste, balanced by the savory, sometimes slightly sweet, flavor of the sausage itself. The sausages are often stuffed tightly into casings, making them plump and juicy, and they’re usually served with fresh accompaniments like whole green chilies, thin slices of ginger, and shredded cabbage. This combination of savory, spicy, and sour flavors creates an explosion of taste that is quintessentially Thai.

While this is the most common version found in places like Bangkok, there are several regional variations that offer different twists on the classic Isaan sausage.

Smaller, Rounder Versions

In some parts of Isaan, you’ll encounter smaller, rounder sausages that are similar to the traditional plump ones but in bite-sized portions. These sausages are often cooked on skewers over charcoal, giving them that irresistible smoky flavor. Once grilled, the sausages are typically served in a small bag with chili sauce and pickled ginger, offering a slightly different twist compared to the typical street-side Isaan sausage. While the core flavors remain the same, the accompanying condiments add a unique touch to each variation.

Naem Sausage: Fermented and Versatile

Another variation of Isaan sausage is Naem, made from minced pork and sticky rice. Unlike the regular Isaan sausages, Naem undergoes a fermentation process lasting about two days, which gives it a much more pronounced sour flavor. While Naem is commonly used as an ingredient in other dishes, like the spicy and sour Yum Naem Khao Thot (a salad made with crispy fried rice balls), it can also be found as street food, skewered and grilled over charcoal. Naem is more commonly known in northern Thailand as part of Lanna cuisine, but it’s also loved in Isaan, where its tangy taste and versatility shine through.

Mum Sausage: A Rare Gem

For something truly unique, the Mum sausage is a must-try. While it’s not as commonly found as other Isaan sausages, it’s a specialty in certain regions, particularly along rural roads between Khon Kaen and Chaiyaphum. Mum sausages are made from pork or beef, often with a more intense sour flavor than regular Isaan sausages. They are drier and crumblier, with a texture similar to the Sai Oua sausages of northern Thailand. Mum sausages are less juicy but have a delightful garlic flavor that sets them apart. Fun fact: the famous Thai actor Mum Jokmok was named after this particular sausage!

Moo Yor: A Northern Thai Twist

Though not exclusive to Isaan, Moo Yor is a sausage found across the region and is more commonly associated with northern Thailand. Resembling the Vietnamese Chả lụa, Moo Yor is a steamed or boiled pork sausage with a firm, white texture. It’s typically used in Thai salads like Som Tam or Yum Moo Yor, a spicy salad made with Moo Yor, chilies, lime, fish sauce, and cilantro. Though Moo Yor may not be as bold in flavor on its own, it pairs perfectly with the fiery heat of Thai salads, adding a mild and refreshing balance to the dish.

A Delicious Journey Through Isaan Sausages

The variety of sausages found in Isaan reflects the rich diversity of Thai cuisine. From the smoky, flavorful Saigrok Isaan to the tangy Naem and dry, garlicky Mum, each sausage offers a unique flavor experience. These sausages are not only a reflection of Isaan’s culinary traditions but also a part of the vibrant street food culture that has made Thai food famous worldwide.

Whether you’re strolling through the streets of Bangkok or venturing to the more rural parts of Isaan, these sausages are a tasty, authentic way to experience the heart of Thai street food. Don’t miss out on trying each regional variation, as they all have something special to offer.
