Instructions

1. 1

   Marinate the fish

   Coat 500 g of bata fish, about seven pieces, with a little turmeric, salt and 1–2 teaspoons of mustard oil. Mix well and leave the fish coated while you prepare the paste.

2. 2

   Make mustard paste

   Grind the black and yellow mustard seeds with the poppy seeds, a few ginger slices, several green chillies and 2–3 cashews, if using. Add ½ teaspoon mustard oil and a little water, then grind to a smooth paste. If you have time, soak the seeds before grinding for 10–15 minutes.

3. 3

   Fry the fish

   Heat 100–150 ml mustard oil in a pan. Fry the fish in batches over medium-high heat, turning once the first side is lightly fried. Give the other side the same light fry; do not fry the pieces until crisp.

4. 4

   Cook the tomatoes

   In the oil used to fry the fish, add 1 teaspoon nigella seeds, 1 teaspoon turmeric and ½ teaspoon Kashmiri chilli powder, and stir briefly. Add the tomatoes and cook over low to medium heat for 1–2 minutes, stirring until they begin to soften and break down.

5. 5

   Cook the paste

   Add the prepared mustard paste and cook it down, stirring, until its raw mustard smell has gone. Season with salt to taste and keep cooking for about 8–10 minutes.

6. 6

   Add water

   Once the raw smell has disappeared, add water as needed for the gravy. Keep the heat at medium, stir to combine and simmer for at least 2–3 minutes, until the sauce comes to a boil.

7. 7

   Simmer the fish

   Lower the heat and add the fried fish pieces. Rather than stirring with a spoon, gently shake or move the pan to mix them into the sauce. Simmer for 4–5 minutes, until the extra water has reduced and the fish is cooked through. Finish with a few slit green chillies.

What is bata macher jhal?

Bata macher jhal is a Bengali fish curry whose name describes a spicy, sauce-based preparation of bata fish. Mustard is a defining flavour in many Bengali fish dishes, and here it gives the gravy its sharp, earthy character.

This version combines black and yellow mustard with poppy seeds, ginger and chillies, then balances the paste with softened tomatoes. The fish is lightly fried first, so it can finish cooking gently in the sauce.

Nutrition and macros by portion

The nutrition label shows one serving as written: 300 calories, 21g protein, 9g carbs, 20g fat.

The fish provides most of the protein, while the tomatoes and any rice served alongside contribute carbohydrates. Mustard oil, frying oil and cashews account for much of the fat. Pair a portion with a generous serving of vegetables and a measured portion of rice for a more balanced plate.

Choosing the fish and mustard

Bata fish: The recipe calls for 500 g, or about seven pieces. Have it cleaned and cut into pieces before starting, and handle it gently when frying and simmering.

Mustard seeds: Black and yellow mustard are ground together for a rounded, assertive paste. Cashews are optional; the recipe uses them to soften the paste's bitterness, while a little mustard oil helps it grind smoothly.

Making a smooth paste

Soaking: If time allows, soak the mustard and other paste ingredients for 10–15 minutes before grinding. Add only a little water at first, then adjust until the paste is smooth enough to cook into the gravy.

Grinding: Mustard can taste harsh if it is overworked or left too coarse. The cashews are optional, but they add a mellow note to the finished paste.

Frying without drying the fish

Oil temperature: Heat the mustard oil well before adding the fish, then fry in batches over medium-high heat. Avoid crowding the pan, which can lower the temperature and make the fish steam.

Light browning: Fry each side only until lightly coloured, as the pieces will cook further in the sauce. Turn carefully so they hold together.

Cooking out the mustard

Tomatoes first: Cook the chopped tomatoes over low to medium heat for 1–2 minutes, until they start to soften. This creates a base for the mustard paste rather than leaving the tomatoes raw in the gravy.

Paste stage: Stir the paste into the tomato mixture and cook for about 8–10 minutes. Look for the raw mustard aroma to fade before adding water; keep stirring so the paste cooks evenly.

Getting the sauce and fish right

Gravy: Add water to suit the amount of sauce you want, then simmer for at least 2–3 minutes until it boils. The final 4–5 minute simmer with the fish reduces excess liquid and lets the flavours come together.

Gentle handling: Once the fish is in the gravy, avoid stirring it with a spoon. Gently move or shake the pan instead, and check that the fish is cooked through without breaking the pieces.

Serving with rice

Serve the curry hot with plain rice, which suits the mustard gravy and makes it easy to enjoy every spoonful. Add a simple vegetable side if you want a more varied plate.

The slit green chillies go in at the end as a garnish. Use fewer or remove them if you prefer a milder finish.

Recipe notes & tips

• Pat the fish dry before marinating so it is easier to fry without spluttering.
• Fry the fish in batches to maintain the pan temperature.
• Add water gradually to the ground paste so it stays smooth rather than watery.
• Cook the mustard paste until its raw aroma fades before adding water.
• Move the pan gently after adding the fish instead of stirring with a spoon.
• Taste the gravy for salt before adding the fish.

Variations

• Milder curry: Use fewer green chillies in the paste and omit the garnish chillies.
• Skip the cashews: Leave them out for a sharper mustard flavour.
• Thicker gravy: Add a little less water and let the sauce reduce during the final simmer.
• More tomato: Add extra chopped tomato for a fruitier, softer-edged sauce.
• Less oil: Use the lower end of the frying-oil quantity and drain the lightly fried fish briefly before adding it to the gravy.

Common mistakes to avoid

• Crowding the pan: The fish may steam rather than fry; cook it in batches.
• Over-frying the fish: It can turn dry before it reaches the sauce; fry each side only until lightly coloured.
• Adding too much water to the paste: The paste can become difficult to cook down; add water a little at a time.
• Rushing the mustard paste: Its raw smell can linger; cook it for about 8–10 minutes until that aroma fades.
• Stirring the fish with a spoon: The pieces can break apart; gently move or shake the pan instead.

How to store

Refrigerate leftovers in a covered container and use within 2 days. Reheat gently in a pan until piping hot, adding a splash of water if the gravy has thickened; avoid vigorous stirring.
