Stink Bean Shrimp Curry (Phat Sato Goong)

Ingredients

Equipment Needed

• •Heavy granite mortar and pestle (krok hin) for pounding the paste
• •Wok (carbon steel preferred)
• •Wok spatula

Instructions

1. 1

   Pound the Southern kreung tam

   Start with the peppercorns in your granite mortar (krok hin). Pound them to a coarse powder. Add the soaked dried chilies and the fresh bird's eye chilies. Pound to a rough paste. Then the garlic and shallots, pounding and scraping the sides of the mortar after each addition. The lemongrass goes in next, then the galangal, then the turmeric. Pound until everything is integrated and the paste turns a deep, vivid gold. The turmeric will stain your mortar, your pestle, your hands, your cutting board. Good. That's how you know you're making a Southern paste. Last, add the kapi. Pound it in until the whole mass is uniform. The paste should be rough but cohesive, deeply aromatic, and aggressively golden.

   Ajarn always said: add ingredients from hardest to softest. Peppercorns first, shrimp paste last. The mortar does the work if you give it the right order. A blender turns this to baby food. You want texture, not puree.

   Prepare the sataw

   Split each stink bean pod open and peel out the bright green beans. They look like oversized fava beans with an attitude problem. Halve each bean lengthwise. This is important: splitting them exposes more surface area to the heat and the paste, which means more flavor absorption and less raw bitterness. Some cooks leave them whole. I split them. The paste should be on the bean, not sitting next to it.

   Fresh sataw should be firm, bright green, and intensely aromatic (the polite word for it). If they're soft or yellowing, they're past their prime. Frozen sataw works if fresh is unavailable, but thaw and pat dry first. The sulfuric punch will be milder, but the dish still holds.
3. 3

   Fry the paste

   Heat the oil in a wok over medium-high heat. When it shimmers, add the curry paste. Fry it, stirring constantly, for about 2 minutes. The paste will sizzle and pop. The oil will turn golden from the turmeric. The kitchen will smell like a Southern Thai market: earthy, spicy, slightly sulfuric from the kapi. You're looking for the oil to start separating from the paste, pooling in golden rivulets around the edges. That separation is your signal. The paste is cooked. If you rush this, the curry tastes raw and gritty. If you nail it, the paste becomes the sauce.

   This step is where the dish lives or dies. Undercooked paste tastes like raw turmeric and gritty shrimp paste. Properly fried paste is fragrant, smooth, and coats the wok in gold. Watch for the oil to break from the paste. That's the moment.
4. 4

   Cook the shrimp

   Increase the heat to high. Add the shrimp and toss them in the paste, coating every piece. Cook for about 1 minute, just until the shrimp start to curl and turn pink at the edges. They should not be fully cooked yet. The residual heat will finish them. Overcooked shrimp in a stir-fry is a crime in any cuisine, but especially in the south where the shrimp come off the boat the same morning.

5. 5

   Add the sataw and season

   Add the halved stink beans and toss everything together. Stir-fry for 2 minutes. The beans should heat through but stay firm with a slight crunch. They're not supposed to go soft. Add the fish sauce and the palm sugar. Toss. The sugar is barely there, just enough to round off the edges, not enough to make it sweet. Southern Thai food does not lean sweet. It leans into sour, spicy, and funky. Add the bruised bird's eye chilies and the shredded kaffir lime leaves. One more toss. Taste. The balance should hit you in this order: salt from the nam pla, heat from the chilies, earthy bitterness from the sataw, funk from the kapi in the paste, with sweetness so faint you almost don't notice it. That's the Southern balance.

6. 6

   Plate and serve

   Plate immediately onto a warm dish. The turmeric-gold oil should glisten across the shrimp and beans. Serve with steamed jasmine rice and nothing else. This dish doesn't need condiments, sides, or garnish. The sataw, the paste, and the shrimp are having a conversation. Don't interrupt it.

Chef Tips

• •Sataw (Parkia speciosa) is the ingredient that separates Southern Thai cooking from every other region. The flavor is sulfuric, bitter, and funky, somewhere between garlic, truffle, and natural gas. That's not a flaw. That's the point. If the smell makes you flinch, you haven't spent enough time in Nakhon Si Thammarat. The south doesn't hold back. Neither does sataw.
• •The Southern kreung tam uses fresh turmeric in quantities that would be unthinkable in Central Thai cooking. Three tablespoons of sliced fresh turmeric in one paste. That golden color isn't cosmetic. Turmeric provides earthy depth and a slight bitterness that balances the kapi. If you can only find dried turmeric, use a third of the volume, but know that the paste will lack the vibrancy and aromatic punch of fresh.
• •Some Southern cooks add a tablespoon of tai pla (ไตปลา, fermented fish innards) or budu (บูดู, Southern fish sauce) to this stir-fry for an extra layer of fermented depth. If you can find either, add it with the fish sauce. The funk amplifies the sataw. But standard nam pla works. The dish doesn't need tai pla to be Southern. The kreung tam and the sataw do that work.
• •Don't overcook the stink beans. They should have bite, a slight crunch when you chew. Mushy sataw tastes of nothing but sulfur. Crisp sataw tastes of sulfur plus bitterness plus the earthy green flavor that makes it addictive. Two minutes in the hot wok, no more.

Advance Preparation

• •The Southern curry paste can be pounded a day ahead and refrigerated in an airtight container. It actually improves slightly as the kapi mellows and integrates overnight. Make a double batch and freeze half for next time.
• •Sataw beans can be shelled and halved up to a few hours ahead. Store in a covered container in the fridge. They oxidize slowly, so don't leave them exposed to air all day.
• •Do not stir-fry the dish ahead of time. The shrimp overcook on reheating and the sataw loses its crunch. Wok to plate to table. That's the timeline.
