Hey everyone! Let’s talk about a fish that’s kind of famous if you’ve spent time near the coasts of Bangladesh or India, especially Cox’s Bazar: Loitta fish, or Bombay Duck as some call it.
Now, this fish is super soft. Like, melt-in-your-mouth tender. Sounds good, right? But that softness makes getting it truly crispy a real challenge. I remember trying it prepared in traditional ways – simple fries, tasty scrambled ‘jhuri’ style – all delicious, but not shatteringly crisp.
So, I got thinking. How can we get that amazing crunch?
The answer? We’re borrowing a trick: a super light, almost lacy tempura-style batter. The secret weapon? Ice-cold soda water. Crazy, right? But it works! It creates this crunchy shell that’s the perfect partner for the soft fish inside.
We’ll also soak the fish in a punchy marinade with spices and sauces, and whip up a zesty mint and cilantro sauce for dipping. It’s maybe not exactly traditional, but wow, the crunch is incredible. Ready to fry up something amazing? Let’s jump in!

Quick Look: What You’re In For
Okay, before we start slinging fish and flour, let’s see what we’re getting into. It’s pretty easy, but frying needs a bit of focus.
Aspect | Details |
---|---|
Total Time | Around 45-50 minutes (Prep: 10-15 min, Marinate: 15-20 min, Fry: 10-15 min) |
Makes | Enough for 4 people as a starter or side |
Scaling? | Yep! Easy to cut in half or double. Just fry big batches in turns. |
Tricky Bits? | I’d say Medium. Handling the soft fish needs care. Frying needs attention. But you can totally do it! |
Stuff You’ll Need:
- A wok or a deep, heavy pan (for the frying)
- A slotted spoon or mesh strainer (to scoop out the fish)
- Mixing bowls (a few for marinade, batter, flour)
- Whisk (for batter)
- Blender or food processor (for the sauce)
- Paper towels or a wire rack (for draining – wire rack is better!)
- Measuring spoons and cups
- Nice to have: A thermometer for the oil (helps get it just right!)
Can You Prep Ahead?
- Sauce: Totally! Make it a day before. Stick it in the fridge in a sealed container. Flavors might even get better!
- Fish: You can wash and cut the fish early, keep it well-drained in the fridge.
- But… The marinating, battering, and frying part? Best done right before you eat. That’s the key to maximum crunch!

Let’s Get Your Ingredients
Alright, ingredient time! Good stuff makes good food, but don’t stress, most of this is easy to find. We’re building flavour layers here!
The Fish & Its Tasty Bath (Marinade):
- Loitta Fish (Bombay Duck): You’ll need 300g. They are naturally very soft. If frozen, make sure they’re fully thawed. Be gentle!
- Flavor Base: 1 tsp garlic & ginger paste (combined). Can’t go wrong with this pair.
- Seasoning: Salt and fresh black pepper (add how much you like). Plus, a pinch of black salt (kala namak) – it has this cool tangy flavour that’s great with fried stuff.
- Spice Kick:
- 1/2 tsp Cajun spice: A little different, adds a nice warmth.
- 1 tsp chili powder: For heat! Use less if you don’t like spicy.
- 1 tsp cumin powder: Earthy goodness.
- 1/2 tsp coriander powder: Bright and citrusy.
- 1/2 tsp chili flakes: Little pops of heat you can see.
- Saucy Goodness: 1 tbsp soy sauce and 1 tsp oyster sauce. Adds that deep savoury flavour (umami!) and a touch of sweet.
- Zing: 1 tbsp fresh lemon juice. Brightens everything up!
Super Important Fish Prep Note: Make sure the fish is really well-drained and patted dry. Water = soggy fish. We want crispy!
The Crunchy Coat (Batter & Dusting):
- The Magic Flour: 150g Tempura flour. This stuff is made for light, crispy coatings. Seriously, try to find it! If not, a mix of rice flour and regular flour is okay, but not quite the same.
- The Fizz: 330ml very cold soda water (sparkling water works too). Cold + bubbles = light batter. It’s science!
- Batter Extras: 1 tsp chili flakes (more flavour!). Optional: 1/2 tsp baking powder for extra puff, but good tempura flour usually doesn’t need it.
- The Dry Dip: Before the wet batter, we need something for it to stick to. Just mix 1 cup all-purpose flour with 2 pinches of salt. Easy!
Batter Secret: Don’t mix it smooth! Lumps are good. Think thin and lacy, not thick like pancake batter.
The Awesome Dipping Sauce:
Every fried thing needs a great sauce, right? This one’s green, fresh, and zesty.
- Herbs: 1/2 cup fresh cilantro (roughly chopped) and 1/2 cup fresh mint leaves (roughly chopped).
- Heat: 2 green chilies (chopped). Take the seeds out if you want less heat.
- Tang: 3 tbsp white vinegar and 2 tbsp fresh lemon juice.
- Balance: 1/2 tbsp sugar.
- Seasoning: Salt (to your taste) and another pinch of black salt.
Sauce Prep: Just chuck all this into a blender and whizz it up until smooth and bright green. Done!

How to Make It: Step-by-Step
Okay, let’s cook! Follow these steps for crispy fish heaven.
Wake Up the Fish: Prep & Marinate
First up, the Loitta. Rinse the pieces under cool water. Now, the important part: pat them really, really dry with paper towels. Get rid of that water! Soggy fish is sad fish.
Put the dry fish in a bowl. Add all those marinade ingredients: garlic-ginger paste, salt, pepper, Cajun spice, black salt, chili powder, cumin, coriander, chili flakes, soy sauce, oyster sauce, and lemon juice.
Gently mix it all up. Use your hands or a spoon, but be gentle. Remember, soft fish! Make sure every piece gets some flavour love.
Let it sit out for 15-20 minutes. Just enough time for the flavours to sink in without making the fish too wet.

Make the Zippy Sauce
While the fish chills, let’s make the sauce. Grab your blender. Toss in the cilantro, mint, green chilies, vinegar, lemon juice, sugar, salt, and that pinch of black salt.
Blend it until it’s a smooth, bright green paste. Smell that? So fresh!
Now, taste it. Always taste it. Need more salt? A bit more sugar? Extra lemon zing? Fix it till you love it. Pour it into a bowl and set it aside. Boom, sauce done.

Get Ready to Fry: Set Up Your Station
Okay, frying time is close! Let’s get organized. This makes everything easier and safer.
First, put your dusting flour (the all-purpose flour with salt) in a shallow dish or on a plate.
Next, get another bowl for the batter. Put the tempura flour, chili flakes, and optional baking powder in it. Give the dry stuff a quick whisk.
Hold up! Don’t add the liquid yet. Wait until the oil is heating up. When you’re just about ready to fry, pour in that ice-cold soda water. Whisk it super quick and gently. Stop when it’s just mixed. Lumps are good! Remember? Overmixing = tough crust. We want light and crispy!
Last thing: get a plate lined with lots of paper towels or (even better!) a wire rack over a baking sheet. Put it right near your stove. This is where your golden, crispy fish will land.


Light the Fire: Heat That Oil!
Time for the main event: hot oil! Pour enough oil (sunflower, canola, vegetable – whatever you like for frying) into your wok or deep pan. You need about 2-3 inches so the fish can float.
Turn the heat to medium-high. Getting the oil temp right is key for crispy, not greasy.
Got that thermometer? Clip it on. Aim for 350°F to 360°F (175-180°C).
No thermometer? Use the batter test. Drop a tiny bit of batter in. Does it sink, then pop right back up, sizzling like crazy? Perfect! Does it sink and stay down, or bubble slowly? Too cold. Wait a bit. Does it turn dark brown super fast? Too hot! Lower the heat, wait a minute, test again.
Safety first! Never walk away from hot oil.

The Big Moment: Dredge, Dip, Fry!
Here we go! Your system should be: Fish -> Dry Flour -> Wet Batter -> Hot Oil.
Take a piece of marinated fish. Let any extra marinade drip off. Roll it gently in the dry flour mix. Coat it lightly all over. Tap off any extra flour.
Immediately dip that floured piece into the lumpy, cold batter. Turn it gently to coat.
Lift it out. Let the extra batter drip off for a second. Carefully lower it into the hot oil. Lay it away from you to avoid splashes.
Repeat with a few more pieces. BUT DON’T CROWD THE PAN! Seriously. This is the #1 mistake. Fry only 4-5 pieces at a time (or fewer if your pan is small). Too many pieces cools the oil down, and you get oily, soggy fish. Yuck.
Watch them sizzle! The batter will puff up and turn golden. This takes about 3-5 minutes per side. Turn them gently once or twice. Listen to that happy frying sound! Smell that amazing smell! The fish cooks super fast inside.

Golden Goodness: Drain, Repeat, Admire!
When a batch looks beautifully golden brown, super crispy, and is floating nicely, use your slotted spoon or strainer to lift them out. Let the extra oil drip back into the pan.
Put the finished Fried Loitta Fish straight onto your paper towels or wire rack. (The rack is best – lets air get underneath so the bottom stays crisp).
Check your oil temp (it might need a minute to get hot again) and keep going with the rest of the fish: dredge, dip, fry, drain.
Work steady, stay safe. Soon you’ll have a pile of perfect, crispy fish. Take a second. Look at what you made! Awesome, right? Now get ready to eat!


Twists & Swaps: Your Fish, Your Way!
This recipe’s great, but feel free to mess with it!
- Gluten-Free? Use gluten-free tempura flour and GF soy sauce (like tamari). Check your other labels, but most stuff should be fine.
- Heat Level: Want it hotter? More chili powder/flakes in the marinade, or keep the seeds in the sauce chilies. Want it milder? Use less chili or none at all.
- Keeping it Casual? Just serve with the sauce. Easy peasy.
- Making it Fancy? Pile it on a nice platter. Add extra cilantro, lemon wedges, maybe some thin-sliced red onion for color.
- Flavor Fun: Swap Cajun spice for Garam Masala for an Indian vibe. Try smoked paprika. A pinch of turmeric in the marinade adds colour (like some traditional recipes).


Serving & Saving (If There’s Any Left!)
Eat this Crispy Loitta Fish Fry hot! Right out of the fryer is best. That’s when the crunch is loudest!
- On the Plate: Pile the fish high. Put the sauce bowl right next to it. Add lemon wedges for squeezing.
- Goes Great With: Awesome on its own as a starter. Or serve with plain basmati rice, pulao, or even fries (fish and chips!). A simple crunchy salad is nice too.
- Leftovers: Okay, honestly? Best eaten fresh. That amazing crisp doesn’t last forever. But if you do have leftovers, fridge them in a sealed container for maybe a day. The sauce lasts 2-3 days in the fridge.
- Reheating: No microwave! It makes them soggy. Try a hot oven (around 375°F/190°C) or an air fryer for a few minutes. They’ll crisp up a bit. Not perfect, but way better than microwaved.
- Freezing? Nah. Probably not a good idea. The batter might get weird when you reheat it. Just make it fresh!


There you go! Everything you need to make crazy delicious, super Crispy Loitta Fish Fry. Have fun cooking, trust your gut, and get ready to crunch! Happy frying!

Instructions
- Prep & Marinate Fish: Rinse Loitta pieces and pat thoroughly dry with paper towels. Place in a bowl. Add all marinade ingredients and toss gently to coat. Let sit for 15-20 minutes.
- Make Dipping Sauce: Combine all sauce ingredients in a blender. Blend until smooth and bright green. Taste and adjust seasoning if needed. Set aside.
- Set Up Frying Station: Mix dusting flour and salt on a plate. In a separate bowl, whisk dry batter ingredients (tempura flour, chili flakes, optional baking powder). Place a wire rack over a baking sheet nearby.
- Heat Oil: Pour oil into a wok or deep pan. Heat over medium-high heat to 350-360°F (175-180°C). Test with a drop of batter – it should sizzle and float quickly.
- Batter & Fry: Just before frying, whisk the cold soda water into the dry batter ingredients – mix briefly, lumps are good! Working one piece at a time: roll marinated fish in dusting flour, dip into tempura batter, let excess drip off, and carefully lower into hot oil.
- Fry in Batches: Fry only 4-5 pieces at a time (don’t overcrowd!) for 3-5 minutes per side, until golden brown and super crispy.
- Drain & Serve: Remove fish with a slotted spoon, letting excess oil drip off. Place on the wire rack to drain. Repeat with remaining fish. Serve immediately!
Notes
- Serving: Best enjoyed immediately while hot and crispy! Serve with the zesty dipping sauce and lemon wedges. Makes a great appetizer or pairs well with rice.
- Key Tips for Crispiness:
- Dry the fish well! Water is the enemy of crisp.
- Use ice-cold soda water for the batter.
- Don’t overmix the batter – lumps mean lightness!
- Don’t overcrowd the frying pan – this keeps the oil hot.
- Drain on a wire rack, not paper towels, to keep the bottoms crisp.
- Storage: These are truly best fresh. Leftovers can be stored in the fridge for 1 day, but they’ll lose crispiness.
- Reheating: Reheat briefly in a hot oven (375°F/190°C) or air fryer to restore some crispness. Avoid the microwave! The sauce keeps well in the fridge for 2-3 days.
