📝 About This Recipe
Som Moo is a quintessential Southeast Asian delicacy, a fermented pork sausage that captures the vibrant, funky, and sour spirit of Northern Thailand and Laos. Through the ancient art of lactic acid fermentation, lean pork and chewy pork skin are transformed into a complex, probiotic-rich snack that balances salt, garlic, and heat. This recipe yields a firm, tangy result that is as much a testament to culinary patience as it is to bold, regional flavors.
🥗 Ingredients
The Meat Base
- 500 grams Lean Pork Loin or Leg (ground very finely, chilled)
- 250 grams Cooked Pork Skin (sliced into translucent, matchstick thin strips)
The Fermentation Catalysts
- 1/2 cup Steamed Sticky Rice (rinsed and cooled to room temperature)
- 1/4 cup Fresh Garlic (pounded into a smooth paste)
- 1.5 tablespoons Sea Salt (non-iodized is crucial for fermentation)
- 1 teaspoon Sugar (to feed the beneficial bacteria)
Flavor & Packaging
- 10-15 pieces Bird's Eye Chilies (whole, kept intact)
- 1 large pack Banana Leaves (cleaned and softened over a flame)
- 1 roll Plastic Wrap (for modern airtight sealing)
- 20 pieces Rubber Bands (to secure the parcels)
👨🍳 Instructions
-
1
Ensure all your equipment, hands, and surfaces are impeccably clean to prevent the growth of unwanted bacteria.
-
2
In a large mixing bowl, combine the finely ground lean pork and the salt. Knead the meat vigorously for 10 minutes; the meat should change texture from loose to very sticky and pasty.
-
3
Add the garlic paste, sugar, and the rinsed sticky rice to the meat mixture. Continue to knead for another 5-10 minutes until the rice is evenly distributed.
-
4
Incorporate the thinly sliced pork skin. Mix and squeeze the mixture through your fingers to ensure the skin strips are fully integrated and not clumped together.
-
5
Test the stickiness: a small ball of the mixture should hold its shape perfectly and feel tacky to the touch. This protein breakdown is essential for the final texture.
-
6
Prepare your banana leaves by cutting them into 6x8 inch rectangles. Briefly wave them over a gas flame to make them pliable and prevent cracking.
-
7
Place a generous tablespoon of the meat mixture onto a piece of plastic wrap. Press one whole bird's eye chili into the center of the meat.
-
8
Roll the plastic wrap tightly into a cylinder, twisting the ends firmly to expel all air. This anaerobic environment is vital for safe fermentation.
-
9
Wrap the plastic cylinder in two layers of banana leaves, folding the ends inward to create a neat, rectangular parcel.
-
10
Secure both ends of the parcel tightly with rubber bands. The pressure helps the meat cure evenly.
-
11
Place the parcels in a container and leave them at room temperature in a dark place for 3 to 5 days, depending on the ambient temperature and desired sourness.
-
12
After 3 days, open one parcel. The meat should be firm, pale pink, and have a clean, sour aroma. If it smells 'off' or looks grey, discard it.
-
13
Once fermented to your liking, move the parcels to the refrigerator to halt the fermentation process.
💡 Chef's Tips
Always use the leanest pork possible; fat can go rancid during the fermentation process and ruin the flavor. If you are nervous about raw fermentation, you can add a tiny pinch of 'Pink Curing Salt' (Prague Powder #1) for extra safety, though it's not traditional. The sticky rice must be rinsed to remove excess starch, which prevents the sausage from becoming unpleasantly slimy. Ensure the pork skin is sliced as thin as possible; thick skin will be too rubbery to enjoy in the finished product. If you live in a very cold climate, the fermentation may take up to 7 days; in the tropics, 2 days is often enough.
🍽️ Serving Suggestions
Serve sliced thinly as an appetizer with raw ginger slices, roasted peanuts, and extra fresh chilies. Crumble the fermented pork into a pan and fry it with eggs for a localized take on an omelet. Use it as the star ingredient in 'Nam Khao,' the famous crispy coconut rice salad. Pair with a cold, crisp lager to cut through the salt and acidity of the pork. Serve alongside fresh cabbage leaves which act as natural wraps for the sour meat and aromatics.
