Walk into any Thai kitchen and you will find, somewhere within arm's reach of the stove, a collection of curry pastes. They might be stored in small containers in the fridge, or in sachets in the cupboard, or in a heavy stone mortar that has been used so many times its surface has turned permanently fragrant. However they are kept, they are the foundation of everything — the concentrated heart of Thai curry cooking, and one of the most sophisticated flavour-building traditions in the world.
Thai curry pastes are not interchangeable. Each one has its own character, its own history, its own set of ingredients, and its own relationship with the finished dish it produces. Understanding the differences between them is not just culinary knowledge — it is the key that unlocks the full range of Thai curry cooking and transforms the way you approach the cuisine.
What a Curry Paste Actually Is
Before exploring the individual pastes, it is worth understanding what a curry paste is and why it matters so much.
A Thai curry paste is a hand-pounded blend of fresh and dried aromatics — chillies, herbs, roots, and spices — reduced to a smooth, intensely flavoured concentrate that forms the flavour base of a curry. Unlike the dry spice blends of Indian cooking, Thai curry pastes are built primarily from fresh ingredients: fresh chillies, fresh lemongrass, fresh galangal, fresh kaffir lime zest. This is what gives Thai curries their brightness and immediacy — their sense of being alive in a way that dried spice blends cannot replicate.
Traditionally, curry paste is made by hand in a heavy granite mortar and pestle, pounding each ingredient in a specific order, working from the hardest and driest to the softest and wettest, until the mixture becomes a uniform, smooth paste. It is slow, physical work — a mortar of paste can take twenty minutes or more of sustained effort — but the texture and flavour it produces is noticeably superior to anything a blender can achieve. The pounding ruptures the cell walls of the ingredients in a way that grinding does not, releasing oils and aromatics more completely and producing a paste that integrates more deeply into the finished dish.
Today, high quality ready-made pastes — like those in the ONOFF range, made from certified organic ingredients — make this foundation accessible without the labour, and without compromising on the authenticity that gives Thai curries their character.
Red Curry Paste: Bold, Bright, and Versatile
Red curry paste is the most widely used and most versatile of all the Thai pastes — the one that most people encounter first, and the one that repays the most exploration.
Its colour comes from dried red chillies, which also provide the paste's characteristic heat — a direct, upfront warmth that arrives quickly and lingers pleasantly. Alongside the chillies, red curry paste contains lemongrass, galangal, garlic, shallots, coriander seeds, cumin seeds, and kaffir lime zest — a combination that produces a flavour that is simultaneously hot, fragrant, citrusy, and earthy.
Red curry is most commonly finished with coconut cream, which softens the heat and adds richness, and it pairs beautifully with almost any protein — chicken, beef, prawns, tofu, and fish all work with equal success. Its versatility makes it the natural starting point for anyone exploring Thai curry cooking, and the depth of a well-made red curry paste means it rewards more experienced cooks equally.
ONOFF's Thai Red Curry Paste captures this balance in its purest organic form — every ingredient traceable, nothing added that does not belong.
Green Curry Paste: The Most Complex and the Most Fierce
If red curry is the most versatile, green curry is the most complex — and, despite its fresh, herbaceous appearance, typically the hottest of the five.
Green curry paste is built on fresh green bird's eye chillies rather than dried red ones, and it is those fresh chillies — used in generous quantity — that give it both its colour and its fierce, immediate heat. Fresh coriander, fresh kaffir lime leaves, lemongrass, galangal, garlic, and shallots complete the base, producing a paste that is intensely aromatic, vibrantly green, and alive with a brightness that no other curry paste can match.
The flavour of a green curry is simultaneously floral, citrusy, herbal, and fiery — more layers happening at once than in any other Thai curry. It is a paste that demands good coconut cream to balance it, and ingredients robust enough to hold their own against its intensity. Chicken, prawns, Thai aubergines, and firm tofu are all natural partners.
Green curry is a relatively recent creation in the context of Thai culinary history — emerging in the early twentieth century as fresh green chillies became more widely used in central Thai cooking. Its youth has not diminished its standing. It is now considered by many Thai cooks to be the pinnacle of the curry maker's art.
Yellow Curry Paste: Gentle, Warming, and Golden
Yellow curry paste is the mildest and most approachable of the five, and the one that shows most clearly the Indian and Muslim influences that have shaped southern Thai cooking over centuries.
Turmeric is the defining ingredient — it gives the paste its warm golden colour and a gentle, slightly bitter earthiness that underpins the whole flavour profile. Alongside turmeric, yellow curry paste contains dried chillies, lemongrass, galangal, garlic, shallots, coriander, and cumin — the last two being spices that arrived in Thailand through the same Indian trading routes that brought curry cooking to the region in the first place.
The result is a curry that is warming rather than hot, rounded rather than sharp, and deeply comforting in a way that makes it particularly appealing to those new to Thai cooking. It pairs beautifully with chicken and potato — a classic combination in Thai yellow curry — and with root vegetables that absorb its golden colour and gentle warmth. Finished with coconut cream, it is one of the most universally loved dishes in the Thai repertoire.
Massaman Curry Paste: Where Thailand Meets Persia
Massaman curry is unlike any other Thai curry, and its paste reflects a history that stretches far beyond Thailand's borders. The name itself is a corruption of "Musulman" — the Thai word for Muslim — and it speaks directly to the Persian and Indian Muslim traders who brought this style of cooking to the southern ports of Thailand centuries ago.
Massaman paste is the most spice-rich of the five, containing ingredients rarely found in other Thai pastes — cinnamon, cloves, cardamom, and star anise alongside the more familiar lemongrass, galangal, and dried chillies. It is these warm, sweet spices that give massaman its extraordinary depth and its distinctly un-Thai character — a curry that feels as connected to the cooking of the Middle East and South Asia as it does to Thailand.
The finished curry is rich, mild, and deeply complex — slow-cooked with beef or lamb and potatoes until everything is tender and the sauce has reduced to something almost sauce-like in its intensity. In 2011, massaman curry was voted the most delicious food in the world by CNN's reader poll — a recognition that surprised no one who had eaten it properly.
Massaman is a curry that rewards patience. It should not be rushed. The long cooking time is not a concession but a requirement — it is what allows the spices to integrate, the meat to soften, and the sauce to develop the kind of depth that makes it one of the great dishes of world cuisine.
Panang Curry Paste: Rich, Concentrated, and Nutty
Panang — sometimes spelled Phanaeng — is the most understated of the five pastes, and for those who discover it, often the most beloved. Where green curry is fierce and complex, Panang is refined and concentrated. Where massaman is warm and aromatic with whole spices, Panang is smooth and deeply savoury with a richness that comes from an unexpected source: roasted peanuts, ground into the paste itself.
Those peanuts are what set Panang apart. They add a nuttiness and body that no other Thai curry paste contains, and they give the finished curry a thickness and creaminess that requires very little coconut cream to achieve. Panang is always served in a relatively small amount of sauce — drier than other Thai curries, almost clinging to the meat rather than pooling around it — which concentrates the flavour further.
The heat in Panang is present but restrained. The dominant notes are richness, sweetness from palm sugar and coconut cream, and the deep savoury quality of the peanuts and the dried chillies together. It is a curry that feels considered and precise — each element doing exactly what it should and nothing more.
Panang is most traditionally made with beef, sliced thinly and barely cooked in the thick, rich sauce, finished with fresh kaffir lime leaves and a drizzle of coconut cream. It is one of those dishes that looks simple and tastes extraordinary.
Five Pastes, One Philosophy
What unites all five pastes — despite their very different characters, origins, and ingredients — is the philosophy behind them. Each one is built to create balance: between heat and fragrance, between richness and brightness, between the deep and the immediate. Each one is designed not to dominate the dish it is in but to provide the foundation from which the finished curry can be built.
That is the art of the Thai curry paste. Not a single flavour, but a structure — a carefully constructed base that gives the cook everything they need to create something harmonious, complex, and deeply satisfying.
ONOFF's full range of organic curry pastes — Red, Green, Yellow, Massaman, and Panang — brings that foundation to your kitchen, made from certified organic ingredients, sourced with care from Thai farms where the quality of every single ingredient is taken seriously. The art of the paste is already done. What you do with it is up to you.
