You’re sitting at a plastic-covered table in a noisy Cantonese restaurant, and it arrives. That pile of golden, craggy seafood nuggets buried under a landslide of fried garlic and searing bird’s eye chillies. We’ve all been there. It’s a staple. But honestly, most of the salt and chilli squid you find in local takeaways is kind of a lie. It’s often rubbery, over-battered, or—worst of all—soggy within five minutes of hitting the plate.
Authentic salt and chilli squid, or chiu yu yau yu, is a masterpiece of texture. It isn't just "fried food." It’s a specific culinary technique that relies on the "dry fry" method. If you don't hear that audible crunch that shatters into a tender, almost creamy center, someone in the kitchen cut a corner.
People think the secret is the salt. It isn't. The secret is the moisture control and the specific type of starch used to create that iconic, glass-like crust.
The Science of the Shatter
Most home cooks make the mistake of using a wet batter. Stop. If you’re dipping squid into a bowl of liquid flour and water, you’re making tempura, not salt and chilli squid. To get that restaurant-quality finish, you need a dry dredge. Specifically, a mix of potato starch and cornstarch.
Why both? Cornstarch provides the structural integrity, but potato starch brings the crunch. Potato starch granules are larger and absorb more water, which leads to a more expansive, crispy surface when it hits 180°C oil.
Then there's the squid itself.
If you use frozen squid rings that have been soaking in a phosphate solution to keep them plump, you’re doomed. That water will leak out the second it hits the heat. You'll end up with a "steamed" coating that slips off the meat like a wet sock. You've got to pat that squid dry. Like, really dry. Use paper towels. Use a hair dryer if you’re feeling dramatic. Just get the water off.
The Salt and Chilli Seasoning Myth
You might see "Szechuan salt" on a menu and think you’re getting something exotic. Usually, it's just toasted Sichuan peppercorns ground with sea salt. But for this specific dish, the "salt" component is rarely just sodium chloride.
In high-end Cantonese kitchens, chefs use a "spiced salt" mix. This often includes:
- Toasted white peppercorns (for that floral, nasal heat)
- Five-spice powder (just a hint, don't overdo it)
- MSG (yes, really—it’s the backbone of the umami punch)
- Dehydrated garlic powder
The "chilli" part is actually two-fold. You have the fresh element—usually thinly sliced bird's eye chillies or long red de-seeded chillies—and the aromatic element. The aromatics are the unsung heroes here. We’re talking about "wok fragrance" or wok hei.
When the squid is finished frying, it gets tossed in a dry wok with fermented black beans, scallions, and fried garlic. This isn't a sauce. There is no liquid. If you see a puddle at the bottom of your salt and chilli squid, the chef failed.

Scoring the Squid: More Than Just Aesthetics
Have you noticed those beautiful diamond patterns on the squid pieces? That’s not just for show. It’s called "pineapple cutting."
By scoring the internal side of the squid mantle in a cross-hatch pattern, you’re doing two things. First, you’re increasing the surface area for the starch to cling to. More surface area equals more crunch. Second, it prevents the squid from curling into a tight, rubbery tube. Instead, it curls into a "blossom" shape that cooks evenly in about 45 to 60 seconds.
Any longer than a minute in the oil and you might as well be chewing on a rubber band.
Why Your Local Takeaway Might Be Cheating
Let’s be real. Consistency is hard. Many places use pre-frozen, pre-breaded squid. You can tell because the coating is thick, uniform, and tastes vaguely like cardboard. Authentic salt and chilli squid should look irregular. Some bits should have more garlic, some should be extra spicy.
Another shortcut? Skipping the garlic frying process.
Real salt and chilli squid features "golden garlic." This is garlic that has been minced and fried separately until it’s crispy and sweet, losing its raw bite. If you’re biting into raw, pungent chunks of garlic, the dish hasn't been balanced correctly. The sweetness of the fried garlic is supposed to counteract the sharp heat of the chilli and the intensity of the salt.
The Health Reality
Is it a health food? No. It’s deep-fried.
However, squid is a fantastic source of protein, vitamin B12, and selenium. The "lifestyle" problem with this dish isn't the squid; it's the oxidized seed oils often used in low-quality deep fryers. When making this at home or looking for a quality spot, the oil matters. Fresh, clean oil with a high smoke point—like peanut or grapeseed oil—ensures the flavor of the seafood shines through instead of a greasy, heavy aftertaste.
How to Spot the Best Salt and Chilli Squid
If you’re hunting for the gold standard, look at the bottom of the plate.
- The Paper Test: If the restaurant puts a piece of greaseproof paper under the squid and it’s soaked in oil, the frying temperature was too low. The oil should be "beaded" on the surface of the squid, not soaked into the meat.
- The Garnish Ratio: There should be almost as much "stuff" (garlic, chilli, onions) as there is squid. You want to be scavenging through the aromatics for those last little crispy bits.
- The Color: It should be pale gold, not dark brown. Dark brown means the oil was old or the starch was burnt.
Misconceptions About Heat
A common mistake is thinking this dish should be "blow your head off" spicy. It shouldn't.
The heat in salt and chilli squid is meant to be a lingering warmth. It’s a "dry heat." Unlike a buffalo wing that hits you with vinegar and immediate spice, this dish builds. The salt opens up your taste buds, the garlic provides a base note, and the chilli provides a tingle. If all you taste is fire, the delicate sweetness of the squid is wasted.
Making It Happen: Actionable Steps
If you want to experience this dish properly—either by cooking it or ordering it—keep these specific points in mind to ensure you aren't getting a subpar version.
- At the Restaurant: Ask if they use fresh or frozen squid. If they say "freshly prepared," ask if it’s a dry starch or a batter. You want the dry starch every single time.
- The Szechuan Factor: If you want an extra kick, ask if they can add toasted Sichuan peppercorns to the mix. The numbing sensation (mala) elevates the salt-and-pepper profile to a whole new level.
- Home Cooking Tip: Do not crowd the pan. If you put too much squid in at once, the oil temperature drops. The starch will turn into a paste. Fry in small batches, about five or six pieces at a time.
- The Recovery: If you have leftovers (rare, I know), do not use a microwave. It will turn the squid into a tire. Use an air fryer at 200°C for exactly three minutes. It’ll bring that shatter-crisp texture back to life.
- The Pairing: Drink something crisp. A dry Riesling or a very cold Tsingtao lager. The carbonation and acidity cut through the fried coating and reset your palate for the next salty bite.
Forget the heavy batters and the soggy rings. The real deal is a light, aromatic, and intensely crunchy experience that focuses on the quality of the seafood and the precision of the fry. Once you’ve had it made with the proper starch-dusting technique and plenty of "golden garlic," those heavy, greasy takeaway versions just won't cut it anymore.
Check the menu for "Salt and Pepper" vs "Salt and Chilli"—usually, they are the same thing, but the addition of "Chilli" specifically implies the use of fresh peppers rather than just dried flakes. Go for the fresh.
