Strip away the coconut milk. Strip away the broth. What's left is the kreung tam, naked and exposed. This is the driest curry in the Thai system, and your paste has nowhere to hide.

Every other curry gives you something to hide behind. Coconut milk softens your mistakes. Broth dilutes a mediocre paste. Phat prik khing gives you nothing. Zero liquid. Just paste, oil, and heat. This is the dish that tells you whether you actually know how to make a kreung tam.
Ajarn always said: the kreung tam is everything. This is the dish that proves it. You pound the paste, you fry it in oil until the oil separates and the kitchen smells like dried chili and kapi and lemongrass hitting hot metal, and that paste coats every long bean, every slice of pork belly. There's no sauce. There's no gravy. The paste IS the dish. If it's good, the whole plate sings. If it's lazy, there's nowhere for lazy to hide.
The four pillars are here, but the balance tilts. Fish sauce for salt. Palm sugar for sweet. Chili for heat, obviously, this is prik khing. But sour? Sour is absent. Not every Thai dish uses all four. The system is flexible. It responds to what the dish needs. Phat prik khing needs the salty-sweet-spicy triangle, with the fragrance of kaffir lime leaves tying it together. No lime juice. No tamarind. Just three pillars and a paste so good it doesn't need the fourth.
I teach this at every Fai Thai workshop because it exposes everything. You can't fake it. The paste is either pounded properly or it isn't. The wok is either hot enough or it isn't. The long beans are either blistered and tender-crisp or they're limp and sad. Principles, not recipes. If your kreung tam is right, the dish takes care of itself.
Phat prik khing is a Central Thai dry curry stir-fry whose name literally means "stir-fried ginger chili," though modern versions often omit the ginger entirely, relying on dried chilies and shrimp paste for depth instead. The technique of frying curry paste directly in oil without any coconut milk or broth places it in the rare category of Thai dry curries (alongside phat phet), making it a street stall and home kitchen staple rather than a banquet dish. Its origins are firmly Central Thai, and the preparation is one of the purest demonstrations of the kreung tam as the sole flavor foundation in the Thai curry system.

•Wok spatula
Instructions
1
Pound the prik khing kreung tam
Start with the hard stuff. Pound the white peppercorns in your granite mortar until they're cracked and fragrant. Add the drained dried chilies and pound until they break down into a rough, fibrous mass. Then the cilantro roots, galangal, and lemongrass, one at a time, pounding each addition until it's incorporated before adding the next. The mortar should be getting crowded and fragrant. Now the shallots and garlic, pounded to a rough paste. Finally, the kapi (shrimp paste) and kaffir lime zest. Pound until everything merges into a coarse, brick-red paste. It should smell like a Thai kitchen, not like a spice cabinet. That smell is the cell walls breaking, essential oils releasing. This takes fifteen to twenty minutes. Your arm will burn. Good.
The order matters. Hard and dry ingredients first, soft and wet ingredients last. If you throw the garlic in before the peppercorns, the garlic turns to liquid while the peppercorns are still whole. Ajarn drilled this into me on day one: build the paste in layers.

Fry the paste
Heat the oil in your wok over medium-high heat. When it shimmers, add all the paste at once. Spread it across the wok surface. Now fry it. Stir constantly. The paste will sizzle and pop as the moisture cooks out. Keep going. After two to three minutes, something happens: the oil separates from the paste and pools around the edges. The paste darkens from brick-red to a deep, almost mahogany color. The kitchen fills with a roasted, funky, intoxicating aroma. That's the signal. The paste is ready.
Oil separation is the most important visual cue in Thai curry cooking. When the paste releases its oil, it means the raw flavors are cooked out and the aromatics have bloomed. If you add the meat before the oil separates, the whole dish tastes raw and pasty. Wait for it.

Cook the pork belly
Crank the heat to high. Add the sliced pork belly directly into the fried paste. Toss and stir-fry, pressing the pork against the wok surface. Every slice should be coated in paste. Cook for two to three minutes until the pork is no longer pink and the fat has started to render and go translucent at the edges. The rendered fat from the pork belly mixes with the paste and becomes part of the sauce. That's why pork belly works here. Lean pork gives you dry curry that's actually dry. Pork belly gives you dry curry that clings.
4
Add the long beans
Throw in the long beans. Toss them aggressively so the paste coats every piece. Stir-fry for another two minutes. You want the beans blistered in spots, tender-crisp, still with a snap when you bite through them. If they're soft and limp, you went too far. Long beans (thua fak yao) are not green beans. They hold up to high heat better and they have a nuttier, denser texture. That's why they're the traditional choice.
5
Season and finish
Add the fish sauce and palm sugar. Toss twice. The sugar melts on contact and creates a slight glaze that helps the paste stick. Add the torn kaffir lime leaves. Toss once more. The leaves should wilt from the heat but stay bright green. They're not garnish. They're a structural aromatic. The citrus fragrance of makrut against the deep, roasted paste is the flavor signature of phat prik khing. Taste. The balance should be: savory-salty from the fish sauce, a gentle sweetness from the palm sugar, heat building from the chilies. No sour. This dish doesn't want sour. Plate over jasmine rice. Eat immediately.
Chef Tips
•Prik khing paste uses dried red chilies, not fresh ones. The dried chilies give you a deeper, roasted heat that can stand up to direct frying without burning into bitterness. Soak them in warm water for fifteen minutes until they're pliable, drain completely, then pound. If there's excess water in the paste, it'll splatter violently when it hits the hot oil.
•Pork belly is traditional and correct. The fat renders into the paste and creates a coating that clings to the long beans. If you use chicken breast or lean pork loin, the dish will taste dry and the paste won't have enough fat to bind. Fat is a flavor vehicle. Ajarn always said: don't fight the fat, work with it.
•The name prik khing translates to "ginger chili," but most modern versions of this dish in Bangkok don't include ginger in the paste at all. Some cooks add a tablespoon of sliced young ginger (khing on). It's not wrong, but it's not required. The name is historical. The paste has evolved.
•Long beans (thua fak yao) are the only correct vegetable here. Green beans are a different species with a different texture. Long beans hold their snap under high heat and have a denser, nuttier bite that matches the intensity of the paste. If you can't find long beans, cut green beans a bit longer and cook them thirty seconds less.
Advance Preparation
•The prik khing kreung tam can be pounded a day ahead and stored in an airtight container in the fridge. Bring it to room temperature before frying. The flavors actually meld and improve overnight.
•Slice the pork belly and cut the long beans up to a few hours ahead. Keep refrigerated. The stir-fry itself takes under ten minutes and should be cooked fresh and served immediately.
