Squid with Salted Egg Yolk (Pla Muk Pad Khai Khem)

Ingredients

Equipment Needed

• •Wok (carbon steel preferred)
• •Spider strainer or slotted spoon
• •Wire rack for draining
• •Cooking thermometer (optional but helpful for oil temperature)

Instructions

1. 1

   Score and prep the squid

   Lay each squid tube flat, inside facing up. Score it in a crosshatch pattern with your knife held at a 45-degree angle, spacing cuts about 5mm apart. Don't cut all the way through. You want to go about two-thirds deep. This does two things: it tenderizes the squid so it doesn't turn to rubber, and it creates surface area for the salted egg yolk sauce to grip. Cut the scored tubes into pieces about 5cm wide. Tentacles stay whole. Pat everything bone dry with paper towels. Moisture is the enemy of a crisp coating.

   When you drop scored squid into hot oil, the pieces curl into beautiful tubes and flowers. That's the crosshatch contracting. It's not just decoration. It's physics. More surface area means more sauce contact, more crunch, more flavor in every bite.
2. 2

   Coat the squid

   In a bowl, whisk the egg white until slightly frothy. Toss the squid pieces in the egg white. In a separate bowl, mix the rice flour, kamin (turmeric), and white pepper. Lift the squid out of the egg white, shake off the excess, and dredge through the flour mixture. The coating should be thin. Paper-thin. You're not making tempura. You're giving the squid just enough texture to hold the sauce and just enough turmeric to stain everything gold. That golden color is the Southern Thai signature. Below the peninsula, kamin replaces galangal as the dominant rhizome. It colors the batter, it flavors the oil, it tells you this is coastal food.

   Rice flour gives a lighter, crispier coat than wheat flour or cornstarch. It stays crunchy even after the sauce goes on. That matters. Soggy squid is a failure of technique.
3. 3

   Fry the squid

   Heat 2 cups of oil in a wok to 180°C (355°F). If you don't have a thermometer, drop a small piece of coated squid in. It should sizzle immediately and float within a few seconds. Fry the squid in two batches. Don't crowd the wok. Each batch takes about 90 seconds. The squid should curl, turn golden from the turmeric, and feel crisp at the edges when you lift a piece with a spider. Pull them out and drain on a wire rack, not paper towels. Paper towels trap moisture on the bottom and kill the crunch you just built.

   Squid cooks in seconds. The moment it curls and turns opaque, it's done. Leave it another minute and you'll have rubber bands. The window between perfect and overcooked is brutally small. Respect it.

   Prepare the salted egg yolks

   While the oil heats, mash the salted duck egg yolks with a fork. They should be dense, bright orange, and slightly crumbly. Work them into a rough paste. Some granularity is fine. You don't want a smooth puree. Those little granules of cured yolk are what give the finished sauce its texture: creamy but with grit. That's the character of khai khem.

5. 5

   Build the egg yolk sauce

   Pour out the frying oil. Wipe the wok. Set it back over medium heat. Add the butter and 1 tablespoon of vegetable oil. When the butter melts and starts to foam, add the mashed egg yolks. Stir constantly. Within 30 seconds, something remarkable happens: the yolks dissolve into the butter and start to foam. The mixture will bubble and expand, turning into a golden, frothy sauce that looks almost like scrambled egg foam. That foam is the sign. It means the salt and fat have emulsified. The yolk proteins are releasing. This is the sauce. Keep stirring for another 20 seconds until the foam is even and fragrant.

   Butter is not traditional Thai. It's the Chinese influence in this dish. The milk solids in butter help the egg yolk emulsify into that signature foam. Oil alone won't give you the same result. This is one of the few Thai dishes where butter earns its place.

   Add aromatics

   The moment the yolk sauce is foaming, throw in the smashed garlic, sliced chilies, and curry leaves. All at once. The curry leaves will crackle and spit in the hot butter. That's the aromatic oils releasing. The smell should hit you instantly: sharp, citrusy, with something green and almost smoky underneath. That's bai karee. That's Southern Thailand in a single leaf. Stir for 10 seconds. The garlic should be fragrant but not browned.

7. 7

   Toss the squid

   Add the fried squid to the wok. Toss everything together with a wok spatula, working quickly. Every piece of squid needs to be coated in that golden egg yolk sauce. The foam clings to the turmeric-stained coating like paint. Add the fish sauce and sugar. Toss twice more. Taste. The salted egg yolks provide most of the salt, so go easy on the nam pla. A tablespoon is a starting point, not a mandate. The sugar is barely a whisper. This is Southern Thai: salty, spicy, rich. Sweet takes a back seat. Total time in the wok from adding the squid: 30 seconds. That's it. Any longer and the coating goes soggy and the squid overcooks.

   Ajarn always said: taste before the dish leaves the wok. Every salted egg yolk is different. Some are saltier, some more mild. Your sauce will vary. Your job is to adjust. Principles, not recipes.

   Plate and serve

   Turn the squid out onto a plate immediately. It should be golden, glistening, flecked with green curry leaf and red chili. Serve with lime wedges on the side and steamed jasmine rice. The lime is the sour pillar showing up at the table, not in the wok. A squeeze of manao over the top cuts through the richness of the egg yolk and butter. It's not optional. It's the balance. Without it, the dish is one-dimensional. With it, all four pillars are present: salt from the egg yolk and nam pla, sweet barely there, sour from the lime, heat from the prik khi nu.

Chef Tips

• •Buy whole salted duck eggs (khai khem) from an Asian grocery, not pre-separated yolks. Crack them yourself. The yolks should be dense, bright orange, and firm. If they're pale or mushy, the eggs weren't cured long enough. Some cooks steam the yolks for 10 minutes before mashing to firm them up and deepen the color. I do this when the yolks are on the softer side. It concentrates the flavor.
• •Curry leaves (bai karee) are not curry powder. They're fresh leaves from the Murraya koenigii tree, used throughout Southern Thailand, Sri Lanka, and South India. In the deep South, near the Malaysian border, curry leaves appear in stir-fries, soups, and even curries. They lose everything when dried. Use them fresh or don't bother. If you can't find them, this dish still works, but you lose the Southern identity. You're making a Bangkok version instead of a coastal one.
• •The squid scoring pattern matters. Crosshatch at 45 degrees, two-thirds depth, 5mm spacing. This is functional, not decorative. It prevents the squid from curling into a tight ball, creates surface area for sauce adhesion, and tenderizes the muscle fibers. Street vendors in Krabi and Nakhon Si Thammarat score fast and clean. Practice on a few pieces. The knife should glide, not saw.
• •This dish is served with jasmine rice, not sticky rice. The richness of the egg yolk sauce needs a fluffy, neutral grain to absorb it. A squeeze of lime over the top is the sour pillar making its entrance at the table. Southern Thai food leans salty and spicy, but the lime at the end is what brings the balance. Don't skip it.

Advance Preparation

• •Squid can be cleaned, scored, and cut up to 4 hours ahead. Keep it refrigerated on a paper towel-lined plate, covered. Pat dry again before coating.
• •Salted egg yolks can be mashed and set aside while you prep everything else. If steaming them first, that can be done up to a day ahead. Refrigerate and mash when ready to cook.
• •Do not coat the squid in flour until you're ready to fry. The coating absorbs moisture and goes gummy if it sits. Coat, fry, sauce, plate. That's the sequence, and it doesn't wait.
