Tom yum's wilder sibling: more seafood, more herbs, more heat, no coconut, no apologies. The same four pillars pushed to their limit in a fisherman's broth that earns its name by overflowing the pot.

Po taek is what happens when the four pillars stop whispering and start shouting.
Ajarn always said that Thai soups are infusion systems. No kreung tam, no paste. Whole herbs, bruised and torn, thrown into hot liquid to release their essential oils directly into the broth. Tom yum does this with restraint. Po taek does it with reckless generosity. More lemongrass. More galangal. More kaffir lime leaves. More chilies. And then, just when you think the herb load is absurd, a fistful of Thai basil (horapha) goes in at the end. It's a soup that pushes the infusion principle to its breaking point, and the name tells you as much: po taek means "the pot broke." The fisherman's catch was so big, so wild, that the pot couldn't hold it.
The seafood is the other story. This isn't a one-protein soup. Shrimp, squid, mussels, fish, sometimes crab. Each protein cooks at a different rate, so timing matters. Shrimp curl in two minutes. Squid goes rubbery in three. Mussels need to open. White fish flakes if you look at it wrong. You add them in sequence, not all at once, and you pull the pot off the heat the moment everything is just done. Overcooking is the enemy.
Fish sauce for salt. Lime for sour. Chilies for heat. A bare touch of palm sugar to round the edges. That's the law. But po taek leans harder into sour and spicy than tom yum does. The sweetness is dialed almost to zero. This is a soup that hits you in the face and doesn't apologize. The lime juice goes in last, off the heat, because heat destroys the bright acid that makes the whole thing sing. Ajarn drilled that into me: "Lime is alive. Kill it with heat and you lose everything."
I first had po taek the way it's supposed to be at a seafood shack in Mahachai, the fishing port outside Bangkok. The cook had a pot the size of a truck tire, half the herbs from the morning market floating in it, and she pulled whole fish out of a styrofoam box with her bare hands. That broth tasted like the ocean had a fight with a Thai garden. It was the most alive thing I'd ever eaten.
Po taek (โป๊ะแตก, literally "broken pot" or "exploded trap") is a Central Thai fisherman's soup that emerged from the coastal communities around the Gulf of Thailand, particularly Samut Sakhon (Mahachai) and Samut Songkhram provinces. The name references the traditional bamboo fish traps (po) that would overflow with the day's catch, and the dish was originally a practical solution: whatever came out of the trap went into the pot with whatever herbs were growing nearby. Unlike tom yum, which settled into a relatively standardized format by the mid-20th century, po taek remains loosely defined, with the defining characteristic being excess: more varieties of seafood, more herbs, and more heat than any other Thai soup.

•Ladle
Instructions
1
Build the seafood stock base
If using head-on shrimp, fry the reserved shells and heads in a splash of oil in your stockpot over medium-high heat until they turn bright orange and fragrant, about 3 minutes. Press the heads with a wooden spoon to extract the oils. Add the water and bring to a boil. Strain out the shells and return the broth to the pot. If you skipped head-on shrimp and are using plain stock, just bring it to a boil. But know that you're starting with half the flavor.
The shrimp shells and heads are free flavor. Toasting them before adding water deepens the broth from something flat to something that actually tastes like the sea. Don't skip this.
2
Infuse the aromatic herbs
Add the lemongrass, galangal, kaffir lime leaves, cilantro roots, dried red chilies, and bruised bird's eye chilies to the boiling stock. Reduce to a strong simmer and let the herbs infuse for 5 minutes. The broth should smell medicinal, sharp, almost aggressive. That's the aromatic trinity (takhrai, kha, bai makrut) doing its work. These herbs go in whole and they stay whole. You infuse them. You don't eat them. If the kitchen doesn't smell like a Thai herbalist's shop, your herbs aren't fresh enough or you didn't bruise them hard enough.
Bruise the lemongrass with the flat of a knife or the base of your pestle. You're cracking the fibers to release the citral and citronellal oils inside. A gentle tap does nothing. Hit it.
3
Cook the proteins in sequence
Add the mushrooms first, let them simmer for 2 minutes. Then add the mussels. They need 3 minutes to open. Next, the fish pieces. Gently. Don't stir aggressively or the fish will disintegrate. Give it 2 minutes. Now the squid rings. One minute, max. Last, the shrimp. They cook in 2 minutes, curling tight and turning pink. The moment the last shrimp curls, you're done. Pull the pot off the heat. Every extra minute past this point is destruction. Squid turns to rubber bands. Fish falls apart. Shrimp become erasers.
Discard any mussels that don't open after 3-4 minutes. They were dead before they went in. This is food safety, not superstition.
4
Season off the heat
With the pot off the heat, add the fish sauce and palm sugar first. Stir to dissolve. Then the lime juice. All of it, off the heat. Lime juice in a hot and sour soup must go in at the end, off the flame. Heat destroys the volatile acids that give lime its brightness. If you boil your lime juice, you get a dull, flat sourness that tastes like nothing. Off the heat, the lime stays alive. Taste the broth. It should hit sour first, salty second, then the slow rising heat from the chilies. The palm sugar should be invisible, just a faint rounding of the edges. If you can taste sweetness, you added too much.
Ajarn always said: "Add sour last, add sour slowly." Lime juice changes the moment it hits. You can always add more. You can't take it back.
5
Finish with Thai basil
Tear the horapha (Thai sweet basil) leaves roughly and throw them into the pot. Stir once. The residual heat will wilt them just enough to release their anise-like aroma without cooking them dead. The leaves should still be green and fragrant when the soup hits the bowl. Ladle generously, making sure every bowl gets a mix of all the seafood and a tangle of herbs floating on top. Scatter fresh cilantro. Serve immediately with steamed jasmine rice on the side. Po taek does not wait. It does not reheat. It lives in the moment between the flame and the table.
Chef Tips
•Po taek is tom yum's unhinged cousin. Both are infusion soups, no kreung tam, whole herbs straight into broth. But po taek pushes everything further: more herbs, more proteins, more heat. If your po taek could be confused with tom yum, you've been too gentle. Double the galangal. Double the kaffir lime leaves. Add Thai basil, which tom yum doesn't use. The excess is the identity.
•Timing the proteins is the real skill here. Every type of seafood has a different clock. Mussels need the most time (3 minutes to open). Fish needs gentleness (2 minutes, no stirring). Squid needs speed (60 seconds, or it's rubber). Shrimp are last (2 minutes to curl). Write this sequence on a piece of paper and tape it to your hood vent until it's in your muscle memory.
•The name po taek (โป๊ะแตก) means 'the pot broke' or 'the trap exploded.' It refers to the bamboo fish traps of the Gulf coast overflowing with catch. The spirit of the dish is abundance and chaos: too much seafood, too many herbs, a broth that barely holds itself together. If your po taek looks neat and composed, you've missed the point. It should look like the ocean threw up in a pot full of herbs. That's the beauty.
•Do not use coconut milk. Po taek is a clear broth soup. Adding coconut turns it into something else entirely. The broth should be transparent with a slight golden hue from the galangal and a faint sheen of oil from the shrimp heads. The clarity is the point. You should be able to see the seafood through the liquid.
Advance Preparation
•Clean and prep all seafood up to a few hours ahead. Keep everything on ice, separated by type, in the order you'll add it to the pot. Once you start cooking proteins, there's no time to prep.
•The shrimp shell stock can be made up to a day ahead and refrigerated. Bring it back to a boil before adding the herbs.
•Po taek cannot be reheated. The seafood overcooks, the lime juice goes flat, the basil turns dark. Make it, serve it, eat it. That's the rule.
