Panang Chicken Curry (Gaeng Panang Gai)

Ingredients

Equipment Needed

• •Heavy granite mortar and pestle (krok), at least 8 inches diameter
• •Wok or heavy-bottomed pan
• •Wok spatula or wooden spoon

Instructions

1. 1

   Toast and grind dry spices

   Heat a dry pan over medium heat. Add the coriander seeds, cumin seeds, and white peppercorns. Shake the pan constantly for 2 to 3 minutes until the coriander turns a shade darker and the kitchen smells like a spice market. The moment you smell it, they're done. Don't walk away. Burnt spices are bitter spices. Transfer to a granite mortar and pound to a fine powder. This is the warm, earthy backbone of Panang paste that separates it from a standard red curry.

   Panang paste includes toasted coriander and cumin, something you won't find in a green or red curry paste. These dried spices give Panang its rounded warmth. They go in first because they need to be powdered fine before the wet ingredients hit the mortar.

   Pound the kreung tam

   Add the drained dried chilies and salt to the mortar with the ground spices. Pound until the chilies break down into a rough paste. Then add the garlic and shallots, pound again. Now the lemongrass and galangal, sliced thin so they break down. Pound until fibrous strands disappear. Add the cilantro roots and kaffir lime zest, pound to incorporate. Next, the shrimp paste, pound until the paste is smooth and fragrant. Finally, the roasted peanuts. Pound them in last so they break down but retain some texture, a slight graininess in the paste. The finished kreung tam should be thick, oily, reddish-brown, and the aroma should fill the room. If it doesn't, keep pounding.

   Ajarn always said: the kreung tam tells you when it's ready. When the aroma fills the room, you're there. Panang paste should smell warm and nutty, not sharp. If it still smells like raw garlic, you're not done. The pounding is the cooking. Thirty minutes is normal. Your arm will know.
3. 3

   Crack the coconut cream

   Pour the thick coconut cream into a wok or heavy pan over medium heat. Do not stir too much. Let it simmer. Watch the surface. After 5 to 8 minutes, the cream will start to separate: you'll see clear, shimmering oil pooling on the surface and the solids will look grainy and slightly curdled. That's cracked coconut cream. That oil is pure coconut fat, and it's where your paste is going to fry. If the cream doesn't crack, your coconut cream wasn't thick enough, or you stirred too much. This step is non-negotiable for every rich Thai curry.

   Use the thickest coconut cream you can find. If using canned, refrigerate the can overnight and scoop only the solid top layer. The thin liquid underneath is your hang kathi (tail of the coconut) for later. The fat content determines whether your cream will crack. Low-fat coconut milk will never separate. It will just simmer sadly.

   Fry the paste

   Add 4 to 5 tablespoons of the kreung tam to the cracked coconut cream. Stir it into the oil. Fry for 3 to 4 minutes over medium heat, stirring constantly. The paste will darken slightly, the oil will turn red-orange, and the aroma will shift from raw to roasted. You'll know it's ready when the oil clearly separates from the paste on the surface. Red-tinted coconut oil floating on top of a concentrated, fragrant paste. That's the moment. That's where the flavor lives.

   If you have leftover paste, pack it into a jar, press plastic wrap directly onto the surface to remove air, and refrigerate. It keeps for a week. Freeze for a month. A proper kreung tam is worth the effort of making extra.

   Cook the chicken

   Add the chicken pieces to the wok. Stir to coat every piece in the fried paste. Cook for 3 to 4 minutes until the chicken is no longer pink on the outside and each piece is stained red-brown with the paste. Add the torn kaffir lime leaves (3 of them, torn in half, central vein removed). Toss once. The leaves will release their citrus oils into the fat immediately.

6. 6

   Reduce the curry

   Add the thin coconut milk, fish sauce, and palm sugar. Stir to combine. Bring to a gentle simmer and cook for 8 to 10 minutes, uncovered, stirring occasionally. The curry should reduce and thicken. You're looking for a sauce that coats the chicken and clings to a spoon, not a soupy broth. If you see liquid pooling at the bottom of the wok, keep reducing. Panang is defined by its thickness. Taste now. Salty from the nam pla, sweet from the nam tan pip, warmth from the dried chilies, richness from the peanuts and coconut. All four pillars present. Adjust. More fish sauce if it needs depth. A pinch more palm sugar if the coconut bitterness is too forward.

   The thin coconut milk here is used sparingly, just enough to loosen the paste and cook the chicken through. This is not a soupy curry. If your Panang looks like a green curry with liquid pooling around the meat, you've added too much. Reduce it further. The paste clings to the meat. That's the standard.

   Finish and serve

   Kill the heat. Transfer the curry to a serving bowl. Scatter the finely shredded raw kaffir lime leaves over the top. Lay the sliced red chili across the surface. Do not stir them in. The raw makrut leaves hit you with a burst of citrus perfume when you eat, cutting through the fat, keeping every bite alive. That's the design. Serve immediately with steamed jasmine rice. Spoon the curry over the rice so the thick paste runs into the grains. That's the way.

Chef Tips

• •Panang paste includes roasted peanuts pounded directly into the kreung tam. This is what gives the curry its signature body and that slightly granular cling. The peanuts aren't a garnish or an afterthought. They're structural. Without them in the paste, your sauce will be thinner and the texture won't coat the meat properly. If someone tells you to sprinkle peanuts on top, they've missed the point.
• •The difference between Panang and red curry is technique as much as paste. Red curry uses more thin coconut milk and is brothy. Panang uses almost all thick coconut cream and reduces until the paste coats the meat. Same cracking technique, completely different result. The system is flexible. Principles, not recipes.
• •Kaffir lime leaves (bai makrut) serve two roles in Panang. The torn leaves that cook in the curry release their oils into the fat. The raw shredded leaves on top provide a citrus burst that cuts the richness at the table. Don't skip the raw garnish. It's the balancing act that keeps the curry from being one-note. Shred them hair-thin, never chop with a knife, tear out the center vein and roll the leaf halves tight, then slice with a sharp blade.
• •Chicken thighs, not breast. Thighs have fat and connective tissue that keep them tender during the simmer. Breast dries out and turns chalky in a reduced curry. This isn't a health food decision. It's a texture decision. The principles say: match the protein to the technique.

Advance Preparation

• •The kreung tam can be pounded a day ahead and refrigerated in an airtight container. Press plastic wrap directly onto the surface to prevent oxidation. The flavors actually improve overnight as the spice oils meld.
• •Chicken can be sliced and refrigerated up to a day ahead. Bring to room temperature 15 minutes before cooking so it cooks evenly.
• •Do not crack the coconut cream in advance. The fat re-solidifies when cooled and you lose the separation. Crack it fresh, right before you fry the paste.
