Isso Wade (Prawn Fritters)
Also known as Isso Vadai
Isso wade, or prawn fritters in English, sometimes written isso vadai, is a crisp Sri Lankan lentil fritter studded with onion, chilli and curry leaves, with a whole prawn pressed on top and deep-fried until lacy and golden. Isso means prawn and wade is the fried lentil snack, so the name is just prawn wade. Hot, crunchy and properly spicy, it's a split-pea and chana dhal fritter you'll see at seaside stalls along the coast, sold by the dozen.
The famous beachside fritter: a crisp, fiery split-pea wade with a whole prawn pressed right on top, eaten hot in your fingers as the waves come in.

About This Dish
There's a particular kind of evening on a Sri Lankan beach where the light goes gold, the sea turns to noise, and a vendor on the sand lifts a fresh batch of isso wade out of a bubbling wok. They sit in a glistening pyramid, each disc the colour of dark honey, each one crowned with a curled pink prawn that fried right into the batter. You buy a few wrapped in paper, eat them too hot, burn your fingers, and understand at once why people come back to the same stall year after year. Isso means prawn and wade is the fried lentil fritter, so isso wade is, plainly, prawn fritters.
Wade belongs to the big family of Sri Lankan short eats, the savoury snacks that fill bakery cases and tea stalls. Within that family there are a few fritters: the soft, ring-shaped ulundu vadai made from black gram, the lentil-and-chilli parippu vadai, and this one, the coastal cousin, where a coarse split-pea batter meets the day's small prawns. It's street food first and foremost, food for beaches and bus stops and rainy afternoons, eaten standing up and never quite formal enough for the dinner table, which is exactly the point.
What sets isso wade apart from its lentil siblings is texture and topping. The batter is ground deliberately coarse, so it fries up open and lacy rather than smooth and dense, all jagged crisp edges that shatter when you bite. On top sits the prawn, pressed in raw so it steams and curls and crisps in the oil while the wade cooks beneath it. The result is two things at once: a fiery, crunchy lentil fritter and a sweet, snappy prawn, brought together by the heat of the wok.
Every coast, every cook, has their own accent. Some grind in dried chilli for a darker heat, some keep it green and fresh, some load on so many curry leaves the batter turns flecked and fragrant. The one constant is that isso wade should be hot in both senses: straight out of the oil and properly spiced, the kind of snack that makes you reach for a second before you've even swallowed the first.
Why Split Peas and a Coarse Batter
The body of isso wade is built on split peas: the yellow or green dried peas you might know as chana dhal in its split-chickpea form, kadala parippu in Sinhala. Soak them for a few hours and they swell and soften, but the trick that makes wade is grinding them coarse, never to a smooth paste. You want most of the peas broken down into a thick, holding batter, with a good number left grainy, almost gritty, so the mix is studded with little nubs of pea. That coarseness isn't laziness, it's the whole texture. When the rough batter hits hot oil, its uneven surface throws out lacy, crisp filaments and the inside stays open and crumbly rather than gummy. That's why a stone-ground wade shatters where a smooth one would sit dense.
The prawn on top is the other half of the dish, and it goes in raw, not pre-cooked. Use a small or medium prawn, peeled or left with the tail on for looks. Press it firmly into each shaped disc just before frying so it bonds as the batter sets. In the oil the prawn does its own cooking: it turns from grey to coral, curls into a tight comma, and crisps at the edges in the same few minutes the wade browns beneath it. Press it in well and the two fry as one piece. Lay it on loosely and it floats off into the oil, which is the most common rookie mistake at the stall and at home.
What It Should Taste Like
A coarse, lacy fritter fried to deep gold that crackles when you bite, chilli-hot and scented with curry leaves and fennel. The centre is savoury and crumbly with split peas, and the whole thing comes topped with a sweet, snappy prawn that has crisped at the edges. Hot from the oil, salty, spicy, impossible to eat just one.

- 01
Soak the Split Peas
Rinse the split peas until the water runs clear, then soak them in plenty of cold water for 3 to 4 hours, until they are swollen and you can crush one easily between two fingers. Drain them well in a sieve.
The soak is what turns hard, rattling dried peas into something you can grind, and the timing decides the texture you're after. Three to four hours swells them just enough to break down into a thick batter while keeping a little bite, which is exactly what a coarse wade needs. Crush a soaked pea between your fingers: it should give and flatten but not dissolve to mush. Skip the soak and the peas grind into hard grit that never softens in the oil. Over-soak them overnight and they go waterlogged, and the batter turns loose and oily.
Tip: Press the drained peas in the sieve to shed clinging water. The drier they start, the less water you add later and the crisper the wade.
- 02
Grind It Coarse, Not Smooth
Grind the drained peas to a thick, coarse batter. Add cold water only a tablespoon at a time, just enough to keep the blades turning. Stop while plenty of broken, grainy bits remain. Do not make a smooth paste.
This is the step that separates a real isso wade from a flat, dense one, and the urge to grind it silky is the one to fight. You want most of the peas crushed into a batter that just holds together, with a good third of them left as visible grain. Run the grinder in short pulses and scrape down between them so you keep control. Pinch a little between your fingers and it should feel gritty and stiff, like wet, lumpy sand, not hummus. That rough, uneven mixture is what fries up open and lacy, throwing out the crisp filaments that make the snack shatter.
Tip: If you've over-blended it smooth, stir through a couple of tablespoons of extra split peas pulsed just once, or a spoon of rice flour, to bring back some grain and grip.
- 03
Mix the Spiced Batter
Tip the coarse batter into a bowl and stir in the rice flour, salt, chopped onion, green and dried chilli, curry leaves, crushed fennel, turmeric and chilli powder. Mix until evenly flecked and the batter holds in a rough scoop.
Add everything at this stage and the batter comes alive. The moment the chilli powder and turmeric hit the bowl, the whole thing turns a warm rust-orange, and the crushed fennel gives off that faint sweet-aniseed scent that's the quiet signature of so much Sri Lankan frying. The rice flour is your insurance: it tightens a slightly loose batter and adds extra crispness to the shell. Keep the batter thick and scoopable, the sort that holds a rough mound on a spoon instead of spreading. If it's loosened from the onion's moisture, don't splash in water, add a little more rice flour instead.
Tip: Taste a tiny pinch of the raw batter for salt and heat. It's just peas and spice, so it's safe to taste. Isso wade is meant to be properly spicy, so be braver with the chilli than feels sensible.
- 04
Prepare the Prawns
Peel the prawns, leaving the tail on if you want the classic look, and pull out the dark vein along the back. Pat them dry, season with a pinch of salt and turmeric, and leave them raw. Don't cook them yet.
The prawns go on raw, and that's deliberate. They cook in the oil at the same time as the wade, so they stay sweet and snappy instead of turning to rubber, which is exactly what happens if you fry them first and then fry them again on the fritter. Drying them matters: a wet prawn presses badly into the batter and spits in the oil. The pinch of turmeric is partly colour and partly the old island habit of taking the raw edge off seafood. Choose small to medium prawns. A giant one will still be undercooked when the wade around it is already deep gold.
Tip: Tail-on prawns look the part and give you a handle, but a fully peeled prawn presses flatter and bonds more securely into the batter. Either is authentic.
- 05
Shape the Wade and Press on the Prawn
Wet your hand, scoop a heaped spoon of batter, and pat it into a thick disc about the size of your palm, either on a wet surface or in your wet palm. Press a prawn firmly into the centre of each one so it sits embedded in the batter.
Picture the beachside stall: the vendor flattens a rough disc, never a neat circle, and plants the prawn dead centre with a firm push of the thumb so it sinks halfway in. That press is everything. Bond the prawn properly and it fries on as one piece. Lay it on lightly and it drifts off into the oil the moment the wade goes in. Wet hands keep the sticky batter from tearing as you work. Keep the discs fairly thick so the middle stays soft and crumbly while the edges crisp, and leave the surface ragged rather than smoothing it, because every rough edge becomes a crunchy lacy bit in the oil.
Tip: Shape each wade just before it goes into the oil rather than building a whole tray ahead, so the soft batter keeps its shape and the prawn stays put.
- 06
Deep-Fry Until Lacy and Golden
Heat oil to medium-hot in a deep pan or wok and slide the wade in gently, prawn-side up, a few at a time. Fry, turning once, until deep golden and crisp and the prawn has curled and turned coral, about 4 to 5 minutes.
Listen for the sizzle the second the wade hits the oil. You want a lively steady crackle, not a violent roar and not a weak fizzle. That crackle is the coarse batter throwing out its lacy edges as the surface moisture flashes off. Medium hot is the target. Oil that's too cool lets the wade sit and soak up fat until it's heavy and greasy. Oil that's too fierce browns the shell before the split-pea centre has cooked through. Fry in small batches so the heat holds and every fritter has room to crisp. The prawn tells you when it's done, turning from dull grey to bright coral and curling tight against the golden wade.
Tip: Fry one wade first as a test. It should sizzle steadily, hold its shape and take 4 to 5 minutes to colour. Sort the heat out before you commit the rest of the batch.
- 07
Drain and Eat Hot
Lift each wade out with a slotted spoon and drain on a rack or plenty of paper while the next batch fries. Serve it immediately, hot from the oil, with lunu miris or a wedge of lime.
Isso wade waits for no one. The whole pleasure is the shattering crisp of the just-fried shell. That crisp starts to soften the moment it cools and steam catches underneath. Drain on a rack, not a flat plate, so the oil runs off and air can circulate. The underside stays crunchy instead of going soggy. This is street food. Eat it standing up, in your fingers, too hot, the way the beach vendors mean it to be eaten. A second batch is always worth frying, because the first never makes it to the table whole.
Tip: Rest the fried wade on a wire rack, never in a closed container. Trapped steam is the fastest way to lose the crunch you just worked for.
Common Mistakes to Avoid
- Grinding the peas to a smooth paste. That gives you a flat, dense fritter instead of an open, lacy one.
- Over-soaking the peas so the batter turns loose and watery and the wade drinks oil.
- Pre-cooking the prawns. That leaves them rubbery after a second fry on the wade.
- Pressing the prawn on too lightly. It floats off into the oil instead of frying onto the fritter.
- Frying in oil that is too cool. This is the single biggest cause of greasy, heavy wade.
- Letting them cool and sit before serving. The crisp shell goes soft.
Serving Ideas
- Hot from the oil in your fingers with a fierce spoonful of lunu miris. That is the classic seaside way.
- With pol sambol and a wedge of lime for a sharp fresh contrast to the spice.
- As a tea-time short eat with a strong cup of Sri Lankan milk tea.
- Piled on a platter as a party snack or starter alongside other short eats.

Storage and Make-Ahead
Best eaten hot and fresh, within an hour or two, while the shell is at its crispest. Cooked wade keep a day refrigerated and crisp up again in a hot oven or air fryer. Avoid the microwave, it turns them soft and chewy. The batter is best ground and fried the same day. It loosens and sours slightly if it sits, though a few hours covered in the fridge is fine.
Two Ways to Cook It
Pulse the soaked split peas in a blender with as little water as possible and leave it deliberately coarse. Keep the spicing simple with onion, green chilli, curry leaves and chilli powder. Press a peeled prawn into each thick disc. Shallow-fry in a couple of centimetres of oil, turning, until golden.
Grind the soaked split peas coarse on a grinding stone or in short pulses. Season generously with green and dried chilli, curry leaves and crushed fennel. Press a tail-on prawn firmly into each rough-edged disc, then deep-fry in a wok in batches for a lacy, shattering shell and a sweet, snappy prawn on top.
Lighter and Healthier Version
Isso wade is street food, proudly deep-fried. But because the body is just split peas, prawn and aromatics, it is already high in protein, and you can lighten the frying without losing the crisp edges and the prawn on top.
Air-Fry Them
Brush the shaped wade lightly with oil and air-fry at 190C/375F for about 12 to 15 minutes, turning once, until golden and the prawn has curled. They come out denser and less lacy than deep-fried, but use a fraction of the oil.
Keep the Batter Thick and Coarse
A thick, well-drained, coarse batter absorbs far less oil even when deep-fried. So good grinding is itself the biggest health win here.
Shallow-Fry Instead
Cook the wade in a couple of centimetres of oil in a frying pan, turning once. They crisp on far less fat than a full deep fry.
Drain Thoroughly
Lift each wade onto a rack or plenty of paper while still hot so the oil runs off rather than soaking back in.
Lean on the Prawn for Protein
Prawns are low in fat and high in protein. So a couple of wade with lunu miris make a more satisfying, balanced snack than the deep fry alone suggests.
