What is thum khao poon

Thum khao poon, a traditional Lao dish, is a spicy rice vermicelli salad. Beloved for its tangy, spicy flavors and fresh ingredients, this staple in Lao cuisine combines fresh herbs, lime, fermented fish sauce, and chilies for a delicious cold noodle salad.

In Thai and Lao, “thum” means to pound or crush, and “khao poon” translates to rice vermicelli noodles.

Lao Rice vermicelli salad

This Lao rice vermicelli salad or tum khao poon is similar to the famous Lao papaya salad, tum mak hoong, or in Thai: tom sum or som tum Thai.

It’s got that same spicy and sour dressing, but instead of papaya shreds, this salad is loaded with slippery noodles that soak up all the tasty dressing.

With the heat from chilies, the sweetness from palm sugar, the sour notes from fresh lime juice, and the umami from fermented fish sauce or padaek, this is Lao food at its finest.

The flavors are easily customizable to personal preference, but the key to any thum salad is striking a balance of flavors: spicy, sour, savory, and sweet.

Isan and Lao cuisine

If you’re wondering why this salad is a staple in both Laos and Isan, it’s because these two cuisines are incredibly similar.

Lao and Isan cuisine are close neighbors in Southeast Asia. Both share a preference for bold, strong flavors, with an emphasis on fresh ingredients. A balance of spicy, sour, sweet, and savory can be found in most of our dishes.

Sticky rice is a daily staple in both regions, and spicy salads are a no-brainer.

The famed papaya salad and dishes like Thai pork larb (minced meat salad) are often enjoyed in both regions, with their own unique regional twist.

Both cuisines make extensive use of umami-loaded fermented fish sauce and spicy chilies like bird’s eye chilies.

And the tradition of using wild ingredients is what sets both kitchens most apart from others. Elder people of Lao and Isan, like my grandmother and grandfather, enjoy cooking with ingredients found in the wild.

Wild mushrooms and even mountain rats are a delicacy in both regions.

Our foods are not just meals but wild stories on a plate!
