Ingredients

• For the soup
• Pork: 1.5 lbs pork ribs (cut into 2-inch pieces). Ribs offer great flavor and tenderness when slow-simmered, contributing to a rich broth. Pork belly or shoulder can also be used.
• Bamboo shoots: 2 cups, thinly sliced.
• Fresh: If using fresh, you'll need to boil them vigorously for at least 30 minutes, changing the water several times, to remove bitterness and ensure they're safe to eat.
• Canned/Jarred: Drain and rinse thoroughly.
• Brined/Fermented: Drain and rinse thoroughly, then boil briefly to mellow the strong flavor.
• Yanang: 1/2 cup fresh yanang leaves OR 2 tablespoons canned yanang extract. Yanang provides the signature earthy-green color and a unique herbal flavor.
• Aromatics:
• 1 stalk lemongrass, smashed and cut into 2-inch pieces
• 2 shallots, peeled and halved
• 3-4 small fresh chilies (like bird's eye), optional, for a kick
• Vegetables (optional but recommended):
• 1 cup pumpkin or kabocha squash, peeled and cubed (adds sweetness and body)
• 1 cup mixed mushrooms (e.g., oyster, shiitake), sliced
• 1/2 cup winter gourd or bitter melon, sliced (adds a subtle bitterness that balances the dish)
• Seasoning:
• 3 tablespoons fish sauce
• 2-3 tablespoons padaek (Lao fermented fish sauce), to taste
• Pinch of salt (adjust after padaek)
• 1 teaspoon sugar (optional, to balance flavors)
• Herbs (fresh, for finishing):
• 1/4 cup rice paddy herb (ngò ôm), roughly chopped
• 1/4 cup Lao basil (or Thai basil), roughly chopped
• For the thickener
• Sticky rice paste: 2 tablespoons glutinous rice flour mixed with 1/4 cup cold water, whisked until smooth. (Alternatively, 1/4 cup cooked sticky rice blended with 1/2 cup water until smooth).

Directions

1. Prep bamboo shoots so they taste clean (and safe)
   1. Fresh: Boil fresh bamboo shoots in plenty of water for 30 minutes, drain, rinse, and repeat this process 2-3 times to remove any natural bitterness and ensure they are safe to eat.
   2. Canned/Brined: Drain and rinse canned or brined bamboo shoots thoroughly under cold water. If using brined, a quick 5-minute boil can mellow their strong fermented flavor.
   3. Thinly sliced: Aim for slices about 1/8-inch thick. This ensures they cook evenly and absorb the soup's flavors beautifully.
2. Start the broth (clean flavor, tender pork)
   1. In a large pot, add the pork ribs and cover with water. Bring to a boil, then immediately drain and rinse the pork. This quick parboil removes impurities, leading to a clearer, cleaner broth.
   2. Return the rinsed pork to the pot, add 6-8 cups of fresh water, smashed lemongrass, and shallots. Bring to a gentle simmer. Cook for 30-40 minutes, or until the pork is nearly tender. Skim off any foam that rises to the surface.
3. Make and add yanang
   1. Fresh leaves: If using fresh yanang leaves, blend them with 1 cup of water until smooth. Strain the mixture through a fine-mesh sieve, pressing out all the liquid. Discard the solids.
   2. Canned extract: Simply measure out the canned yanang extract.
   3. Add the yanang liquid to the simmering pork broth. This should be done early to allow the herbal flavors to infuse the broth and achieve its characteristic color.
4. Add bamboo + vegetables in the right order
   1. Add the prepared bamboo shoots to the pot. Simmer for 10-15 minutes.
   2. Next, add any longer-cooking vegetables like pumpkin/kabocha. Cook for about 10 minutes.
   3. Finally, add quicker-cooking items like mushrooms or gourd, cooking until just tender, usually 5-7 minutes.
5. Season with fish sauce + padaek (the “don’t ruin it” step)
   1. Stir in the fish sauce.
   2. Then, add 2 tablespoons of padaek. Stir gently and taste. Padaek is potent, so add it gradually, tasting after each addition, until you reach your desired level of savory funk. Adjust with a pinch of salt or sugar if needed. Avoid over-stirring once padaek is added, as this can sometimes make the soup cloudy.
6. Thicken with sticky rice paste (no lumps)
   1. Ensure your sticky rice flour slurry is whisked smooth with no lumps.
   2. While stirring the soup constantly, slowly stream in the sticky rice paste. Continue to stir gently until the soup lightly thickens.
   3. What “lightly thickened” looks like: The soup should have a slightly viscous, velvety texture that lightly coats the back of a spoon, not a thick gravy. It will also appear slightly cloudy.
7. Finish with herbs + serve
   1. Remove the pot from the heat. Stir in the fresh rice paddy herb and Lao basil. Adding them off-heat preserves their vibrant color and fresh aroma.
   2. Do a final taste check and adjust any seasonings if necessary.
