Lao Som Moo
Fermented Sour Pork
Lao Som Moo is a beloved fermented sour pork sausage, a staple in Lao cuisine. It's made from ground pork, pork skin, garlic, cooked sticky rice, and chilies, which are mixed and then formed into logs to ferment for several days. The result is a tangy, savory sausage with a unique texture, often enjoyed as a snack, with sticky rice, or incorporated into salads like Nam Khao.

๐ง Ingredients
- 1 lb Lean pork meat
- 7 oz Pork skin
- 5 cloves Garlic, minced
- 1 cup Cooked sticky rice
- 2 tsp Salt
- to taste Fresh chilies, whole or sliced
๐จโ๐ณ Instructions
- 1
If using fresh pork skin, boil it in water for about 20 minutes until tender. Drain, remove any excess fat, and slice into thin strips.
๐ก Tip: Ensuring the pork skin is clean and free of fat is crucial for proper fermentation. - 2
Trim any visible fat from the lean pork meat. Mince the pork meat finely using a cleaver, food processor, or meat grinder.
๐ก Tip: Using lean pork is important as fat can spoil during fermentation. - 3
In a large mixing bowl, combine the minced pork, sliced pork skin, minced garlic, cooked sticky rice, and salt. Knead the mixture thoroughly by hand for about 5-10 minutes until it becomes sticky and well-combined.
๐ก Tip: Kneading is essential to develop the sticky texture that binds the ingredients. - 4
Divide the mixture into portions. For each portion, flatten it slightly, insert one or more whole or sliced chilies into the center, and then shape it into a tight log or sausage shape.
๐ก Tip: Adding chilies inside ensures they are distributed throughout the sausage. - 5
Wrap each log tightly in plastic wrap or banana leaves. Ensure there are no air pockets.
๐ก Tip: Tight wrapping helps maintain the shape and prevents spoilage. - 6
Store the wrapped sausages at room temperature in a dark place for 2 to 4 days to ferment. The exact time depends on the ambient temperature; a sour aroma indicates readiness.
๐ก Tip: Warmer temperatures will speed up fermentation. Check for a tangy smell and slightly reddish color. - 7
Once fermented, transfer the Som Moo to the refrigerator to slow down the fermentation process. It can be eaten raw or lightly cooked.
๐ก Tip: Consume within a week of refrigeration for best quality.
๐ก Pro Tips
- โEnsure all ingredients, especially the pork, are very cold when mixing to prevent premature spoilage.
- โThe amount of chili can be adjusted to your spice preference.
- โIf you don't have access to pork skin, you can increase the amount of pork meat, but the texture will be different.
