Ingredients

• 1.5 lbs boneless, skinless chicken thighs, thinly sliced (or thin-sliced pork shoulder/loin for a `pork swap`)
• 6 cups water or low-sodium chicken broth
• 2 stalks lemongrass, tough outer layers removed, bruised/smashed and cut into 2-inch segments
• 1.5-inch piece galangal (or best-possible substitute, see Variations), thinly sliced
• 4-5 makrut lime leaves, torn in half to release aroma
• 1 shallot, thinly sliced
• 2 cloves garlic, minced
• 2-4 fresh Thai chilies, bruised or thinly sliced (adjust to desired heat level)
• 2 tablespoons tamarind concentrate/paste, dissolved in 1/4 cup warm water (start with 1.5 tbsp, add more to taste)
• 3-4 tablespoons fish sauce (start with 3 tbsp, adjust to taste)
• Pinch of sugar (only if needed to round out sour/sharp edge)
• 1 cup sliced mushrooms (e.g., oyster, straw, or button), optional
• 1 small tomato, cut into wedges, optional
• 3-4 tablespoons `natural lime juice`, freshly squeezed (added at the end)
• 1/4 cup fresh cilantro, chopped, for garnish
• 2-3 scallions, thinly sliced, for garnish

Directions

1. Prep the Aromatics: Carefully remove the tough outer layers from the lemongrass stalks. Using the back of a chef's knife or a mortar and pestle, bruise or smash the lemongrass until fragrant. Cut it into 2-inch segments. Thinly slice the galangal and tear the makrut lime leaves in half to help release their oils. Have your sliced shallot, minced garlic, and bruised/sliced Thai chilies ready.
2. Infuse the Broth: In a medium stockpot, combine the water or broth with the prepared lemongrass, galangal, makrut lime leaves, shallot, garlic, and Thai chilies. Bring the mixture to a gentle simmer over medium heat (avoid a hard boil, which can make the herbs bitter). Let it simmer for 10-15 minutes, allowing the aromatics to infuse the liquid until the broth is wonderfully fragrant.
3. Cook the Chicken: Add the thinly sliced chicken (or pork) to the simmering broth. Cook for 3-5 minutes, or until the chicken is just cooked through. If any foam rises to the surface, skim it off with a spoon.
4. Build the Sour Base: Reduce the heat to low. Stir in the dissolved tamarind concentrate gradually, adding about half first. Taste the broth. Tamarind provides a complex, fruity sourness. Add more tamarind concentrate a little at a time until you reach your desired level of tanginess.
5. Season to Balance: Stir in 3 tablespoons of fish sauce. Taste again. Fish sauce adds essential saltiness and umami depth. If the soup tastes too sour or has a sharp edge, add a tiny pinch of sugar to round out the flavors.
6. Finish Bright: If using, add the sliced mushrooms and tomato wedges. Simmer for another 2-3 minutes until they are tender. Then, turn off the heat. This is crucial: add the fresh `natural lime juice` after removing the soup from the heat to preserve its bright, fresh flavor. Stir in half of the chopped cilantro and sliced scallions.
7. Serve: Ladle the hot Tom Som into individual bowls. Garnish with the remaining fresh cilantro and scallions. Serve immediately with steamed jasmine rice or rice noodles on the side.
