Ingredients
- 4 cups Fish stock or water
- 12 oz White fish fillets (cod, snapper, or tilapia)
- 3 whole Roma tomatoes
- 2 tablespoons Tamarind paste
- 1.5 tablespoons Fish sauce
- 2 whole Red Thai chili peppers
- ¼ cup Fresh cilantro leaves
- ¼ cup Fresh Thai basil or regular basil
Instructions
- 1
Cut each tomato from stem to opposite end into quarters; you'll have 12 wedge-shaped pieces total. Leave the seeds inside.
- 2
Slice each red chili lengthwise from stem to tip into two long halves, leaving the seeds inside for heat.
- 3
Pat the fish fillets dry with paper towels, then cut them against the grain into 2-inch chunks, roughly the size of walnuts.
- 4
Pour 4 cups of fish stock into a large pot and set it over medium-high heat until small bubbles rise steadily from the bottom, about 5 minutes.
- 5
Stir in 2 tablespoons of tamarind paste until completely dissolved into the stock; the liquid will look slightly thicker and smell tangy.
- 6
Pour in 1.5 tablespoons of fish sauce and stir until evenly combined; taste and adjust if it needs more salt or sourness.
- 7
Add the 12 tomato wedges and 2 chili halves to the pot; let them float in the stock without stirring for 3 minutes so they begin to soften.
- 8
Gently slide the fish chunks into the soup, being careful not to break them apart; they will sink at first.
- 9
Maintain medium heat and let the soup simmer without stirring for 4 minutes, until the fish turns opaque white throughout when you break a piece open with a fork.
- 10
Scatter 0.25 cup of fresh cilantro leaves across the surface of the soup in a loose pile.
- 11
Scatter 0.25 cup of fresh basil leaves on top of the cilantro in a separate pile so both herbs are visible.
- 12
Ladle the soup into two bowls, ensuring each bowl receives fish, tomato, chili, broth, and a mix of both herbs.
