You’re at a gastropub. You order the salt and chilli calamari because it’s the safest bet on the menu. Then it arrives. It's either a pile of rubber bands or a greasy, beige mess that slides out of its breading the second you poke it with a fork. It’s frustrating. We’ve all been there, and honestly, it’s a crime against seafood.
Making this dish at home sounds easy, right? It's just squid and some spice. But there is a reason professional chefs in Cantonese kitchens spend years mastering the "wok hei" required to get that perfect, shattering crispness. Most home recipes fail because they treat calamari like chicken nuggets. It isn't chicken. It’s a delicate, water-heavy cephalopod that wants to turn into a bouncy ball the moment you look at it wrong.
If you want to actually nail that restaurant-quality crunch, you have to stop overthinking the spice and start obsessing over the moisture.
The Moisture Myth and the Secret of Szechuan Pepper
Most people think the "salt" in salt and chilli calamari is just table salt. It isn't. Not really. If you just toss some Morton’s on there, you’re missing the floral, numbing complexity that defines the dish. Authentic versions—rooted in the "Salt and Pepper" (Jiao Yan) tradition of Cantonese cuisine—rely on a mix of toasted Szechuan peppercorns and sea salt.
The Szechuan pepper provides a "mala" sensation. It's not "hot" like a habanero; it’s buzzy. It vibrates on your tongue. When you combine that with the heat of fresh red chillies, you get a multi-dimensional burn that makes you want to keep eating.
But here is the real kicker: moisture is the enemy.
Squid is roughly 80% water. When you throw it into hot oil, that water wants to escape. If it escapes through your batter, the batter steams from the inside out. Result? Soggy calamari. To prevent this, you have to dry the squid. I mean really dry it. Use paper towels. Use a hair dryer if you have to. If the surface of the squid is damp when it hits the flour, you’ve already lost the battle.

Why Your Flour Choice Is Probably Wrong
Forget all-purpose flour. Just put it back in the pantry.
If you use standard wheat flour, you’re developing gluten. Gluten is great for bread, but it sucks for fried seafood because it creates a chewy, heavy crust. Professional kitchens almost exclusively use cornstarch (cornflour), potato starch, or a blend of both.
Potato starch is the secret weapon here. It has larger starch granules than cornstarch, which creates a rougher, more "nubbly" surface area. More surface area equals more crunch. Some chefs, like J. Kenji López-Alt, have experimented with adding a tiny bit of baking powder to the mix. This creates microscopic air bubbles that lighten the coating, making it shatter rather than crunch. It’s a game-changer.
The Art of the Prep: Cleaning and Scoring
Don’t buy the pre-frozen rings if you can avoid it. They’re often treated with phosphates to keep them "plump," which basically means they’re pumped full of extra water. Buy whole tubes.
Cleaning a squid is a bit gross, sure, but it's worth it. You pull the head, remove the beak, and slide out the "pen"—that weird, clear plastic-looking internal shell. Once you have the tube, don't just slice it into boring circles.
- Slice the tube open so it lays flat.
- Score the inside of the flesh in a diamond pattern.
- Don't cut all the way through!
- Cut the scored flesh into bite-sized squares.
When these hit the oil, they won't just sit there. They will curl up into beautiful, pinecone-like shapes. This isn't just for aesthetics. Those scores create dozens of little ridges that catch the salt, the toasted garlic, and the chilli flakes. It maximizes the flavor-to-surface-area ratio.

Temperature: The 180°C Rule
You need a thermometer. I’m serious. If you try to eyeball the oil temperature, you’re playing Russian roulette with your dinner.
If the oil is too cool (below 170°C), the squid sits there and soaks up grease. If it’s too hot (above 195°C), the starch burns before the squid is cooked. The sweet spot for salt and chilli calamari is 180°C (350°F).
You’re flash-frying. This isn't a long soak. We’re talking 60 to 90 seconds. Any longer and you're eating rubber. You want the coating to be pale gold, not deep brown.
The Second Fry: Is it Necessary?
Some people swear by the double-fry method. You fry it once at a lower temp to cook it, then a second time at a higher temp to crisp it. For thick-cut fries? Absolutely. For delicate calamari? Honestly, it’s risky. You risk overcooking the squid. If you get your starch blend and your initial oil temp right, a single, fast fry is usually superior for keeping the seafood tender.
The "Dry Fry" Finish
The biggest mistake people make is tossing the fried calamari into a wet sauce. Don't do that. You just spent all that effort getting it crispy.
Instead, you do a "dry fry" in a separate wok or pan.

- Sauté your aromatics (garlic, ginger, spring onions, and plenty of fresh red chillies) in a tiny bit of oil.
- Once they smell incredible and the garlic is just starting to turn golden, kill the heat.
- Toss the fried squid into the pan.
- Sprinkle your salt and Szechuan pepper mix over everything.
- Toss it fast.
The residual heat will stick the aromatics to the crust without making it soggy. It’s a 10-second process. If you take 30 seconds, you’ve overcooked it.
Common Misconceptions About Squid
There’s a persistent myth that "small squid is tender, big squid is tough." It’s a half-truth. While baby squid are indeed delicate, large Humboldt squid can be incredibly tender if handled correctly—often through a process of "tenderizing" using papaya juice or milk (the enzymes break down the tough connective tissue).
However, for salt and chilli calamari, you want medium-sized Loligo squid. They have the right thickness to stand up to the high heat of a deep fry without disappearing into the crust.
Another weird one: "Squid should smell like the ocean." No. Fresh squid should barely smell like anything. If it has a "fishy" odor, it’s already oxidizing. Walk away. Your local fishmonger is your best friend here. If they’re willing to clean it for you, even better, but make sure they don't soak it in water afterward.
Troubleshooting Your Batch
- The coating is falling off: Your squid was too wet, or you didn't press the starch into the flesh firmly enough.
- It’s too salty: Remember that you’re seasoning at the very end. Start with less than you think you need. You can always add, but you can't subtract.
- The chilli is overwhelming: Remove the seeds. Most of the heat lives in the pith and seeds. If you want the flavor without the fire, just use the red skins.
- It's chewy: You cooked it for 2 minutes instead of 1. It happens fast. Watch the clock.
Actionable Steps for Your Next Attempt
To get this right tonight, follow this specific workflow. Do not skip steps.
- Prep the Spice: Toast 1 tablespoon of Szechuan peppercorns and 1 tablespoon of sea salt in a dry pan until fragrant. Grind them into a fine powder. Set aside.
- Dry the Squid: Pat your cleaned squid pieces with paper towels. Leave them on a wire rack in the fridge for 30 minutes uncovered. This "air-dries" the skin perfectly.
- The Starch Blend: Mix 70% potato starch with 30% cornstarch. Add a pinch of white pepper.
- The Aromatics: Finely mince three cloves of garlic, one red bird’s eye chilli, and two spring onions.
- The Fry: Heat neutral oil (peanut or vegetable) to 180°C. Toss the squid in the starch, shake off every bit of excess, and fry in small batches for 75 seconds.
- The Toss: In a hot wok with a teaspoon of oil, flash-fry the aromatics for 20 seconds, add the squid, hit it with the salt/pepper mix, and serve immediately.
This isn't just dinner; it's a timing exercise. Once you see the squid curl and the starch turn into that crisp, white-gold shell, you’ll never go back to the soggy pub version again. Eat it while it’s hot—calamari waits for no one.
