Step 2
- a.Marinate and Fry the Fish

- c.In a bowl, rub the fish pieces with 1/2 tsp of turmeric powder and 1/2 tsp of salt, ensuring they are evenly coated.
- d.Heat 1/4 cup of mustard oil in a kadai or heavy-bottomed pan over medium-high heat until it just begins to smoke. This removes its raw pungency.

Step 5
- a.Simmer and Finish
- b.Once the gravy is boiling, gently place the fried fish pieces into the curry.
- c.Reduce the heat to a low simmer. Let the curry cook for 5-7 minutes, allowing the fish to absorb the tangy flavors. Do not stir too much to prevent the fish from breaking.
- d.Taste and adjust the salt if necessary. The consistency should be a thin, soupy gravy.
- e.Turn off the heat and garnish with freshly chopped coriander leaves. Let the curry rest for 5 minutes before serving for the flavors to meld.
What to keep in mind.
5 tips from the recipe — small details that make a real difference to the final dish.
- 1For authentic flavor, use mustard oil and heat it until it's lightly smoking before adding ingredients. This tempers its pungent flavor.
- 2Patting the fish completely dry before marinating ensures it fries well and doesn't splatter too much in the hot oil.
- 3Do not over-fry the fish. A light golden color is sufficient, as it will continue to cook in the gravy.
- 4The tanginess of Ou Tenga can vary. Adjust the amount of pulp based on your preference for sourness.
- 5Simmer the fish gently in the gravy. Vigorous boiling can cause the delicate fish pieces to break apart.
