Grilled Squid with Seafood Sauce (Pla Muk Yang)

Ingredients

Equipment Needed

• •Charcoal grill or gas grill
• •Sharp knife for scoring
• •Granite mortar and pestle (krok hin) for the sauce
• •Grill tongs
• •Wire grill brush

Instructions

1. 1

   Score the squid

   Lay each squid tube flat, inner side up. With a sharp knife held at a 45-degree angle, score diagonal lines across the flesh about 5mm apart. Don't cut all the way through. You want to go about two-thirds deep. Rotate the squid 90 degrees and score again, creating a crosshatch diamond pattern. This isn't decoration. The crosshatch does three things: it increases surface area for the marinade, creates channels where char and smoke can penetrate, and causes the squid to curl open on the grill so heat distributes evenly. Physics, not presentation.

   If your knife drags instead of gliding, it's dull. A dull knife tears squid flesh instead of scoring it cleanly. The torn edges will toughen on the grill. Sharpen your knife first.

   Marinate with turmeric

   In a bowl, combine the turmeric, vegetable oil, ground white pepper, and the teaspoon of fish sauce. Rub this mixture over every surface of the scored squid tubes and tentacles. Your hands will turn yellow. That's how you know you're doing it right. Let it sit for 15 minutes at room temperature. The turmeric needs time to penetrate the score marks and bond with the protein. Don't skip this. Unmarinated squid on a grill is just... cooked squid. The kamin gives it that golden Southern Thai color and a layer of warm, earthy bitterness that balances the natural sweetness of fresh squid.

   Fresh turmeric (kamin sot) is always better than powder if you can get it. Grate it on a microplane. The color is more vivid, the flavor is brighter, and the aroma has a gingery sharpness that powder loses in the drying process. Southern Thai vendors always use fresh.

   Pound the nam jim talay

   While the squid marinates, make the sauce. In a mortar, pound the garlic, cilantro roots, and chilies to a rough paste. Not smooth. You want texture, small pieces that will suspend in the liquid. Scrape the paste into a bowl. Add the fish sauce, lime juice, and palm sugar. Stir until the sugar dissolves. Taste it. The balance for Southern Thai should lean sour and spicy, with salt supporting and sweetness barely there. This isn't Central Thai. The palm sugar is a whisper, not a presence. If the lime doesn't hit you first, add more. If the chilies don't build heat in the back of your throat, you didn't use enough. Stir in the chopped cilantro leaves last.

   Cilantro root (rak phak chi) is critical. It provides a depth and earthiness that the leaves can't replicate. If you can't find roots, use the lower stems close to the root. But try to find the roots. Thai and Southeast Asian grocers carry cilantro with roots still attached.

   Grill over high heat

   Get your charcoal grill ripping hot. You want direct, intense heat. If you're using a gas grill, crank it to maximum and let the grates heat for ten minutes. Brush the grates with oil. Lay the squid tubes scored-side down first. Don't touch them. Two minutes. The scored flesh will open up, the edges will char, the turmeric will darken to a deep amber. Flip once. One more minute on the other side. The tentacles go on at the same time, they cook faster, maybe ninety seconds total, turning once. Pull everything the moment the flesh is opaque and the char lines are defined.

   Charcoal is not optional if you want this to taste like the coast. Gas grills work but they don't give you that smoky, slightly acrid edge that coconut-husk charcoal provides. In Southern Thailand, vendors use coconut shell charcoal. It burns hotter and cleaner than briquettes.

   Slice and serve

   Transfer the squid to a cutting board. Let it rest for thirty seconds, no more. Slice each tube into rings or strips about 1cm wide. The crosshatch scoring should be visible on each piece, curled open and showing the char pattern. Arrange on a plate with the tentacles. Serve the nam jim talay alongside in a small bowl. Jasmine rice on the side. That's it. Fire and the sea, nothing in between. Let the sauce do the work. Dip every piece.

Chef Tips

• •Squid has a brutal timing window. Undercooked squid is translucent and slimy. Perfectly cooked squid is opaque, tender, with a slight chew. Overcooked squid is rubber. The difference between perfect and ruined is about thirty seconds on a hot grill. Watch it like it owes you money. The moment the flesh turns fully opaque and the scored lines open wide, pull it off.
• •The nam jim talay should be made fresh every time. The lime juice loses its brightness within an hour. If you make it ahead, leave the lime juice out and add it just before serving. The pounded garlic-chili-cilantro root base can sit for a couple of hours, but the acid goes in last. Ajarn always said: add sour last, add sour slowly.
• •Scoring depth matters more than pattern. If you barely scratch the surface, the marinade doesn't penetrate and the squid won't curl properly on the grill. If you cut too deep, the squid falls apart. Two-thirds of the way through the flesh. Practice on one tube first. You'll feel the resistance change as the knife approaches the outer wall.
• •Southern Thai grilled seafood is always served with nam jim talay, never with sweet chili sauce. That bottled stuff you see at tourist restaurants has no place here. The pounded sauce is the four pillars in liquid form: salty, sour, spicy, barely sweet. It's the Southern Thai grillmaster's signature. Every vendor's nam jim is slightly different, and that difference is their identity.

Advance Preparation

• •Squid can be cleaned, scored, and marinated up to 2 hours ahead. Keep refrigerated and covered. The turmeric will penetrate deeper with more time, which is fine.
• •The nam jim talay base (pounded garlic, chilies, cilantro root) can be prepared up to 3 hours ahead. Add the fish sauce, palm sugar, lime juice, and cilantro leaves just before serving. The lime must be fresh.
• •If buying whole squid, clean them the morning of. Pull the head and tentacles from the tube, remove the cartilage (the clear plastic-looking quill inside), peel off the purple outer membrane. Rinse everything under cold water. Pat dry. Fresh squid should smell like the sea, not like fish. If it smells fishy, it's not fresh enough.
