Ingredients
For the Tamarind Juice
- 1/3 cup tamarind pulp
- 1 cup boiling water
For the Broth
- 2 tbsp oil
- 2 tbsp finely chopped lemongrass
- 1 medium tomato (sliced into 1-inch thick slices)
- 1/4 pineapple (peeled and cut into chunks, about 1 cup chunks)
- 4-5 cremini mushrooms (quartered)
- 6 cups water
- 2 lemongrass stalks (slightly crushed)
- 1/4 cup granulated sugar
- 3 tsp salt
- 1 tsp mushroom seasoning (optional but recommended)
- 6 pieces fried tofu
- 1/4 Thai chili (finely sliced)
For Serving
- Cooked white rice noodles (round rice noodles preferred)
- A handful of Thai basil
- Vegan bologna (or vegan sausages, optional)
Instructions
- Prepare Tamarind Juice: Add the tamarind pulp to a large bowl and pour in the boiling water. Stir with a wooden spoon to dissolve the pulp and let it sit for about 10 minutes.
- Strain Tamarind Juice: Using a fine-mesh sieve, strain the tamarind liquid into a separate container, discarding the solid pulp. Set the clear tamarind juice aside.
- Sauté Aromatics and Fruits: Heat 1 tablespoon of oil in a large pot over medium heat. Add the finely chopped lemongrass, sliced tomatoes, and pineapple chunks. Sauté for about 5 minutes until the tomatoes soften and the mixture becomes fragrant.
- Add Mushrooms: Add the quartered cremini mushrooms to the pot and sauté for an additional 2 minutes to integrate flavors.
- Add Water and Lemongrass Stalks: Pour 6 cups of water into the pot and add the slightly crushed lemongrass stalks, bringing the mixture to a boil.
- Add Tamarind Juice and Seasonings: Stir in the tamarind juice, granulated sugar, salt, and mushroom seasoning. Mix well to combine all flavors.
- Add Protein and Optional Greens: Incorporate the fried tofu pieces and vegan bologna slices (if using). You may also add chopped morning glory, green beans, or other greens of your choice at this stage.
- Simmer the Broth: Reduce the heat to low and let the broth simmer uncovered for 25-30 minutes to develop depth of flavor. Taste and adjust saltiness or sweetness as needed. Before serving, add finely sliced Thai chili to the broth if you prefer some heat.
- Cook Noodles: While the broth simmers, bring a pot of water to a boil and cook the rice noodles according to package instructions. Drain noodles once cooked and divide them into serving bowls.
- Assemble Bowls: Using a slotted spoon, distribute mushrooms, fried tofu, pineapple, and any greens evenly into each bowl over the noodles.
- Pour Broth and Garnish: Ladle the hot tamarind broth over the ingredients in each bowl and garnish with fresh Thai basil leaves.
- Serve: Serve the soup immediately with additional chopped chili on the side for an extra kick if desired.
Notes
- For extra spice, increase the amount of Thai chili or add chili oil when serving.
- Mushroom seasoning is optional but adds a nice umami depth to the broth.
- Feel free to customize with your favorite vegetables or greens like morning glory or green beans.
- Use fresh tamarind pulp for the best authentic flavor; tamarind paste can be a substitute but adjust quantity to taste.
- Round rice noodles are traditionally used, but any rice noodles or even vermicelli can work well.
- This soup is vegan and can be made gluten-free by choosing gluten-free soy or seasoning alternatives.
