What Is Som Tum Mua?
Som Tum Mua is a heartier version of Thai green papaya salad commonly found in the northeast of the country, where Isaan cuisine is famous for its bold flavors and spicy food.
While Som Tum Thai is slightly sweet and lighter, Som Tum Mua is deeper, funkier, and more savory. The word mua loosely means “mixed together,” which perfectly describes the dish. Vendors toss in whatever delicious ingredients they have on hand.
Typical Ingredients in Som Tum Mua
Som Tum Mua starts with shredded papaya, the main ingredient of this bold Isaan papaya salad. It is mixed with fermented fish sauce, long beans, cherry tomatoes, dried shrimp, and soft rice noodles.
- Green papaya. The main ingredient of Som Tum Mua. Use firm unripe papaya with pale green skin and crisp flesh, shredded into thin strips.
- Rice vermicelli noodles. Soft cooked thin noodles that make this version of som tum more filling.
- Long beans. Cut into short pieces for crunch and fresh flavor.
- Cherry tomatoes. Add juiciness and balance the spicy dressing.
- Garlic. Pounded first to create the aromatic base of the salad.
- Thai chilies. Provide the heat that defines this spicy Isaan dish. Adjust to your own preference.
- Fresh lime juice. Adds bright acidity that balances the salty dressing.
- Thai fish sauce. Provides clean salty depth and classic Thai flavor.
- Fermented fish sauce (Pla Ra). A traditional Isaan ingredient that gives Som Tum Mua its bold savory taste.
- Palm sugar. Adds a light sweetness that balances the lime juice and fish sauce.
- Tamarind concentrate. A traditional tangy sauce for loaded Som Tum.
- MSG. Optional but commonly used in Isaan papaya salads to enhance the overall flavor.
- Dried shrimp. Adds concentrated umami and a slightly chewy texture.
- Toasted peanuts. Provide nutty crunch and extra texture.
- Pickled mustard greens. A common addition in Som Tum Mua that adds tangy depth.
- Shredded carrot. Adds color and mild sweetness to the salad.
- Moo Yor or fish balls. Optional but traditional in many Som Tum Mua variations. These Vietnamese style pork sausage slices or fish balls are usually found in the freezer section of Asian markets. See notes below.
Optional Additions (Street Vendor Style)
Many street vendors customize Som Tum Mua with extra toppings depending on what they have available. You may also see it served with boiled eggs, pork rinds, shrimp, cabbage, Thai eggplants, water spinach, or additional long beans.
Moo Yor
Moo Yor is a Vietnamese style pork sausage that’s commonly added to Som Tum Mua. It’s already fully cooked, so it only needs thawing and slicing before serving. Many Thai and Isaan vendors add it directly to the salad or serve it on the side as a garnish for extra savory flavor and texture.
How to Shred Papaya for Som Tum
Street vendors usually cut papaya with a knife to create thin julienned slivers. At home, a kiwi peeler, a julienne peeler, mandoline with a julienne blade, or food processor works well.
After shredding the papaya, soak it briefly in cold water and dry it with a paper towel. This keeps the Som Tum salad crisp. If you're new to this ingredient, you can also read my guide on how to cut papayas.
Instructions
- Pound garlic and chilies. Add garlic and Thai chilis to a mortar and pound until fragrant.
- Add vegetables. Add long beans and cherry tomatoes. Pound lightly to bruise them.
- Season the dressing. Add fermented fish sauce, Thai fish sauce, lime juice (throw in the rind too), palm sugar, MSG. Stir and pound lightly until the palm sugar dissolves. You should have a nice brown papaya salad dressing in the mortar.
- Add shredded papaya and vegetables. Add the shredded green papaya, shredded carrot, and pickled mustard greens, sliced Moo Yor, fish balls along with the dried shrimp. Toss and lightly pound so the dressing coats the papaya strands.
- Add noodles. Mix in the cooked rice noodles, crushed pork rind and dried shrimp. Toss everything together using a spoon and pestle.
- Taste and adjust. Adjust with more lime juice, fish sauce, or chilies based on your own preference. Serve immediately with sticky rice.
