Machha Patua
A light, tangy fish curry from Odisha where delicate fish fillets are gently poached in a fragrant paste of mustard, garlic, and green chili, finished with a refreshing burst of raw mustard oil. This no-onion, no-tomato dish comes together quickly and pairs beautifully with plain steamed rice.

1.Drain the soaked yellow mustard seeds.2.Grind mustard seeds with garlic cloves and 2 slit green chilies to a smooth paste using 3 tbsp water. Scrape down sides as needed.TIPGrind to a very smooth paste. Gritty mustard paste will ruin the texture of the curry. - prep

Simmer the mustard base.
Pour 2 cups of hot water into a kadai. Stir in the mustard paste, remaining salt, and bring to a gentle simmer over medium heat. Cook for 8 minutes, stirring occasionally, until the raw mustard smell fades.
- temper · ~2 min
Make the tempering.
Heat 2 tbsp mustard oil in a small pan until it reaches smoking point and turns pale yellow. Remove from heat briefly, add panch phoron and let it crackle for 30 seconds. Immediately pour the tempering into the simmering mustard curry base.
TIPGetting the oil to its smoking point is key to removing the raw pungency of mustard oil and unlocking its nutty flavor. - simmer · ~7 min
Poach the fish.
Gently slide the marinated fish pieces into the simmering gravy along with the remaining slit green chili. Do not stir. Cover and simmer on low heat for 6-7 minutes until the fish is just cooked through.
TIPDon't stir once the fish is added — it's delicate and will break. Gently shake the pan instead if needed. - garnish
Finish with raw mustard oil and coriander.
Turn off the heat. Drizzle 1 tsp raw mustard oil on top and sprinkle with chopped coriander leaves. Cover and let it rest for 5 minutes before serving.

Serve hot with steamed rice.
Ladle into individual bowls, ensuring each portion has fish and a generous amount of the thin, tangy gravy.
What to keep in mind.
8 tips from the recipe — small details that make a real difference to the final dish.
- 1Soak the mustard seeds in warm water for a full 15 minutes to ensure a smooth, non-bitter paste when ground.
- 2Grind the mustard-garlic paste very finely; any graininess will ruin the delicate texture of the curry.
- 3Bring the mustard oil to its smoking point before tempering to mellow its raw pungency and unlock a nutty aroma.
- 4Do not stir the curry after adding the fish; gently shake the pan or tilt it to distribute the gravy instead.
- 5Let the finished curry rest for 5 minutes off the heat so the fish absorbs the flavors without overcooking.
- 6For the freshest taste, use fish steaks with skin-on, as they hold together better during gentle poaching.
- 7Serve immediately with hot steamed rice—this dish does not reheat well because the fish becomes dry.
- 8Adjust the number of green chilies to control heat; the recipe as written is moderately spicy.
Adapt it for your goals.
Milder Version
Reduce green chilies to 1 and use only half the raw mustard oil drizzle to dial down the heat while keeping the core mustard flavor intact.
Fish SwapFish Swap
Replace rohu with any firm white fish like tilapia, pomfret, or catfish; adjust cooking time as thinner fillets may need only 4-5 minutes.
Oil Free FinishOil-Free Finish
Skip the final raw mustard oil drizzle for a lower-fat option; the tempering oil already provides enough richness and flavor.
Vegan AdaptationVegan Adaptation
Substitute fish with 400g of firm tofu or king oyster mushroom slices; marinate and poach the same way, though omit the fish and use vegetable stock in the base.
