Thai food has a reputation for being complex — and in some ways, it is. The flavours are layered, the ingredients specific, and the balance between sweet, sour, salty, and spicy demands a certain attention that not every cuisine asks of its cook. But the techniques themselves? They are largely accessible, logical, and once understood, transformative. You do not need a professional kitchen, a lifetime of experience, or even particularly specialist equipment. You need to understand how a handful of core methods work — and why they produce the results they do.
Master these, and Thai cooking opens up entirely.
Pounding the Paste: Why the Mortar Matters
Before there is a curry, there is a paste. And before there is a paste, there is a mortar and pestle — the most important piece of equipment in a traditional Thai kitchen, and the technique that underpins everything built around it.
Pounding is not the same as blending. A blender cuts ingredients into uniform pieces; a mortar and pestle crushes and bruises them, rupturing the cell walls and releasing oils, juices, and aromatic compounds in a way that no blade can replicate. The result is a paste with a depth and complexity — a slightly coarse, fibrous texture and an intensity of fragrance — that blended pastes simply cannot match. Thai cooks will tell you they can taste the difference immediately, and they are right.
The technique requires patience. You work from the hardest ingredients to the softest, pounding each one until it is fully broken down before adding the next. Lemongrass first, then galangal, then garlic and shallots, then the chillies, then the softer aromatics. Each ingredient is incorporated before the next is added. The process takes ten to fifteen minutes of sustained effort, but the paste it produces is the foundation of the entire dish.
For everyday cooking, a good quality ready-made paste — like ONOFF's organic curry pastes — is the practical solution that sacrifices nothing in authenticity. But understanding why the mortar matters changes how you use even a premade paste: you treat it with more care, bloom it properly in hot oil, and recognise the craft behind it.
Cracking the Coconut Cream: The First Step of Every Curry
One of the most important techniques in Thai curry cooking is almost invisible — and it is the step that separates a flat, one-dimensional curry from one with genuine depth and complexity. It is called cracking the coconut cream, and it is where every well-made Thai curry begins.
Coconut cream, when heated slowly in a dry pan or wok, begins to separate. The fat splits from the solids, leaving a pool of clear coconut oil in which the curry paste can then be fried. This process — known in Thai as แตกมัน (taek man), literally "breaking the fat" — blooms the aromatics in the paste in a way that adding them to water or thin liquid never could. The heat of the fat carries the flavour of the paste deep into the dish before the liquid is ever added.
The visual cue is clear: when the coconut cream has cracked properly, you will see the oil pooling around the edges of the paste and a slightly glossy sheen across the surface of the pan. This is the moment to add your protein or vegetables. Do not rush it. The five minutes this step takes repays itself many times over in the finished dish.
ONOFF's Coconut Cream is rich enough in fat content to crack properly — a detail that matters more than most people realise when they reach for a can.
Stir Frying at High Heat: Speed, Smoke and the Wok
Thai stir frying — pad — is one of the most recognisable cooking techniques in Southeast Asian cooking, and one of the most commonly misunderstood by home cooks outside the region. The misunderstanding is usually the same: not enough heat.
Authentic Thai stir frying happens at temperatures that most domestic hobs struggle to reach. Street food vendors and restaurant kitchens use powerful gas burners that produce an intense, concentrated flame capable of heating a wok to temperatures that create what Chinese and Thai cooks call wok hei — the slightly smoky, caramelised quality that gives great stir fried dishes their characteristic flavour. It is produced by the rapid vaporisation of moisture and the Maillard reaction happening simultaneously at very high heat.
At home, the way to get closest to this is to use your hob's largest, most powerful burner, preheat your wok until it is visibly smoking before adding any oil, and — crucially — cook in small batches. Overcrowding the pan drops the temperature immediately, turning a stir fry into a steam, killing the caramelisation and producing a watery, flat result. Cook less at a time, move quickly, and keep the heat as high as your equipment allows.
The other non-negotiable is mise en place — everything cut, measured, and ready before the wok goes on the heat. Stir frying happens in two to three minutes. There is no time to chop a garlic clove once you have started.
Balancing the Dressing: The Heart of Thai Salads
Thai salads — yum — are not dressed in the Western sense. There is no vinaigrette whisked separately and poured over at the end. The dressing is built directly in the bowl, tasted, and adjusted until the balance is right, and then the ingredients are added and tossed through it. The sequence matters, and the tasting is everything.
The base of almost every Thai salad dressing is the same: fish sauce for salt and depth, lime juice for sourness, palm sugar for sweetness, and fresh chilli for heat. The ratios vary by dish and by personal preference, but the principle is constant — each element should be present, none should dominate, and the whole should taste complete.
The technique is in the adjusting. Add the fish sauce first, then the lime, then the sugar. Taste after each addition. If it is too sharp, add a little more sugar. If it is flat, add more lime. If it lacks depth, a touch more fish sauce. The dressing is finished when it tastes balanced — when no single flavour is jumping out above the others. That balance is the dish. ONOFF's No Fish Vegan Seasoning Sauce and Thai Rice Vinegar are reliable, consistent building blocks for this process — clean enough in flavour to make the adjusting straightforward.
Steaming: Gentle Heat, Preserved Nutrition
Steaming is one of the oldest and most widely used techniques in Thai cooking — and one of the most underappreciated by cooks who associate it only with health food or bland results. In Thailand, steaming is used for everything from sticky rice and fish to custards, dumplings, and whole cakes.
The technique is simple but the results depend on getting a few things right. The steam should be vigorous before the food goes in — a gentle trickle produces uneven cooking. The food should never touch the water below. And the lid should seal well enough to keep the steam concentrated around the food rather than escaping constantly.
For sticky rice — one of the most important applications of steaming in Thai cooking — the grain must be soaked overnight before steaming, a step that cannot be skipped. The soaking softens the grain and ensures it cooks evenly throughout its twenty-five minute time in the basket. The result is chewy, fragrant, and nothing like the overcooked, gummy result that comes from boiling glutinous rice in water.
Grilling: Patience Over the Flame
Thai grilling — yang — is not about speed or high heat. It is about patience. The great grilled dishes of Thai cooking — gai yang, moo ping, satay — are all cooked slowly over medium heat, turned regularly, and allowed to caramelise gradually rather than char quickly. The goal is meat that is cooked through with a lacquered, slightly sticky exterior where the sugars in the marinade have caught the heat and turned golden.
The marinade is essential and always applied well ahead of cooking — overnight whenever possible, so the aromatics have time to penetrate the meat. Lemongrass, coriander root, garlic, white pepper, fish sauce, and a touch of palm sugar are the classic building blocks. The sugar in the marinade is what creates the caramelisation; the aromatics are what give it its Thai character.
At home, a hot griddle pan with a little patience produces excellent results. Resist the urge to turn the meat constantly — let it sit, develop colour, and release naturally from the surface before turning. The oven finish method — searing on the griddle and completing in a 180°C oven — gives reliable, evenly cooked results for larger pieces like chicken thighs or drumsticks.
The Finishing Touch: Fresh Herbs Added at the End
One detail that distinguishes Thai cooking from many other cuisines is when the fresh herbs go in. In Thai cooking, fresh herbs — holy basil, coriander, mint, spring onion — are almost always added at the very end of cooking, off the heat or in the final thirty seconds, so their fragrance and colour are preserved rather than cooked away.
This is especially important in pad krapow, where the holy basil goes in only after the heat has been turned off, wilting in the residual warmth of the pan rather than frying. The difference between basil added at the beginning and basil added at the end is not subtle — it is the difference between a green, fragrant, alive dish and one that smells faintly of cooked vegetables.
The same principle applies to coriander on a finished curry, mint on a laab, and lime leaves sliced paper-thin over a bowl of soup. These are not garnishes in the decorative sense. They are the final layer of flavour — and in Thai cooking, that last layer matters as much as the first.
Putting It Together
None of these techniques exists in isolation. They are part of the same philosophy — the same commitment to freshness, balance, and the careful treatment of good ingredients that defines Thai cooking at every level. Understanding them does not just make you a better Thai cook. It makes you a more attentive cook in general, more aware of heat and timing and the difference between rushing a dish and letting it develop.
Thai cooking rewards patience and punishes shortcuts. But it rewards generously — with food that is vivid, fragrant, and deeply satisfying in a way that is very hard to achieve by any other means.
Pad Pak Boong — Stir Fried Morning Glory
Cooks in 15 minutesPad pak boong is one of the great Thai street food dishes — and one of the most underrated. Morning glory, known in Thai as ผักบุ้ง (pak boong), is a semi-aquatic leafy vegetable with hollow stems and tender leaves that wilts beautifully in a screaming hot wok, absorbing the salty, garlicky sauce in seconds. At street food stalls across Thailand, it is tossed in the wok at extraordinary heat — sometimes theatrically flipped high into the air, earning the dish its nickname "flying vegetables" — and arrives at the table blistered, fragrant, and deeply satisfying. It is the kind of dish that reminds you how much a handful of simple ingredients can achieve when the heat is right and the timing is perfect.
