A short tour of Asia’s most definitive spicy sauces
Long before chillies arrived in Asia via colonial trade routes in the 16th century, the region already understood heat—through ginger, peppercorns, mustard seeds and fermentation. When New World chillies took root, they were absorbed into existing systems of preservation and seasoning rather than treated as novelties. What emerged were spicy sauces that do more than burn: they age, bloom, crunch, sting, linger and define. Across Asia, spice became less about intensity and more about balance and structure. Think about memorable spicy dishes and imagine how heat is carried, softened, sharpened or delayed.
These spicy sauces are not interchangeable; they are cultural technologies, shaped by climate, trade, necessity and local taste.

Gochujang (Korea)

Gochujang developed during the Joseon Dynasty, when chillies—newly introduced from the Americas—were folded into Korea’s already sophisticated fermentation culture. Made from chilli powder, glutinous rice, fermented soybeans and salt, it matures slowly, developing sweetness alongside heat. Rather than functioning as a finishing sauce, it forms the backbone of definitive Korean dishes like bibimbap, tteokbokki and countless stews. Its thickness allows it to cling, coat and dissolve gradually, shaping an entire dish rather than punctuating it. Globally, it has moved from speciality shops to restaurant kitchens, often used as a marinade or glaze where depth is needed more than fire.

Doubanjiang (China)
Often described as the soul of Sichuan cooking, doubanjiang originates from Pixian, where fermented broad beans and chillies are aged for years under the sun. The result is salty, funky and deeply savoury, with heat that unfolds slowly. It provides the colour and base note for dishes like mapo tofu and twice-cooked pork, anchoring Sichuan’s famously complex taste profiles. Unlike fresher chilli-based spicy sauces, its power lies in restraint—used sparingly but unmistakably. Internationally, it has become essential in Chinese restaurant kitchens, though rarely substituted successfully.
Yuzu kosho (Japan)
Yuzu kosho emerged in Kyushu, blending green chillies with salt and the aromatic zest of yuzu citrus. The paste ferments briefly, preserving brightness rather than deepening funk. Its heat is clean and direct, lifted by citrus oils that cut through fat with precision. Traditionally paired with grilled meats, hot pots and sashimi, it acts more like seasoning than sauce. As Japanese cuisine gained global attention, yuzu kosho followed, finding its way into Western kitchens seeking sharpness without heaviness.
Chilli crisp (China)
Chilli crisp rose to prominence through contrast: heat tempered by crunch, oil carrying flavour rather than smothering it. Popularised by Lao Gan Ma in Guizhou, it combines fried chillies, garlic, onions, peanuts and fermented black beans. It isn’t meant to coat but to scatter. Toss is over noodles, eggs, vegetables, even plain rice. Its global popularity lies in its adaptability; it behaves more like a condiment than a sauce. Today, it has inspired countless variations, though the original remains a reference point.
Sichuan chilli oil (China)
Unlike chilli crisp, Sichuan chilli oil is about infusion rather than texture. Chillies are bloomed in hot oil with aromatics like star anise, cinnamon and Sichuan peppercorns, extracting both heat and numbing spice. The oil is vivid, fragrant and fluid, designed to slick noodles or pool at the bottom of soups. Its role is to perfume and stimulate, not distract. Outside China, it has become shorthand for “mala,” a trending flavour that Gen-Z go for. However, the best versions remain tightly controlled in balance.
Chiu Chow chilli oil (Hong Kong)
Common in teahouses and dim sum restaurants, Chiu Chow chilli oil is restrained compared to its mainland counterparts. It emphasises garlic and dried chillies over aggressive spice blends, producing a cleaner, more focused heat. Served alongside poached meats and dumplings, it complements rather than dominates. Its clarity reflects Cantonese preferences for purity and balance. While less famous globally, it remains quietly influential in professional kitchens. Squeeze some lemon over it and that delightful zest will give it an extra dimension.
Sambal (Indonesia / Malaysia)

Sambal predates chillies, but its modern form revolves around them, pounded fresh with shrimp paste, lime and aromatics. Sambal terasi, one of the most common versions, is assertive—salty, fermented and unapologetically sharp. It’s not smoothed or refined; its texture is part of its impact. Served alongside grilled fish, rice or vegetables, it resets the palate with every bite. Globally, sambal has resisted standardisation, retaining its regional and personal variations.
Nam prik pao (Thailand)
Often called chilli jam, nam prik pao is built through roasting rather than fermentation. Chillies, shallots and garlic are charred, then blended with tamarind and palm sugar, creating smoke, sweetness and depth. It forms the red sheen of tom yum and adds body to stir-fries and noodles. Unlike sharper chilli pastes, it rounds dishes out rather than cutting through them. Its flavour profile has quietly shaped Thai food abroad, even when unnamed.

Achar (India)
Some spicy sauces are dry and relish-based. For example, Indian pickles trace their roots to preservation, using salt, acid and oil to extend harvests. Mango, lime or chili are cured with mustard oil and spices, developing intensity over time. Achar isn’t spooned generously; it’s dabbed, meant to punctuate rice or flatbread. The heat is blunt and bracing, softened only by familiarity. Beyond India, achar has found admirers for its concentration and longevity.
Lunu miris (Sri Lanka)
Lunu miris is made by pounding dried chillies with cured Maldive fish, onions and lime. The mixture is dry, coarse and intensely savoury, designed to be scattered rather than spread. Traditionally eaten with hoppers or rice, it brings salt and heat without oil or sugar. Its flavour reflects island preservation methods and resourcefulness. Outside Sri Lanka, it remains underrepresented, though chefs increasingly reference it.
Podi / gunpowder (South India)
Podi comes to the table a dry blend of roasted lentils, chillies and seeds, ground coarse and mixed with oil at the table. It originated as a practical accompaniment, shelf-stable and adaptable. When combined with ghee or sesame oil, it becomes a textured paste with layered heat. Served with idli or dosa, it offers contrast rather than sauce-like cohesion. Its influence is subtle but enduring, especially in vegetarian cooking.
Si racha chilli sauce, AKA sriracha (Thailand)
Si Racha sauce originated in the seaside town of Si Racha, where it was developed as a light, pourable condiment for seafood rather than a catch-all heat source. Though sriracha is known the world over, the original Thai version is thinner and brighter, built on fermented chillies, vinegar and sugar, with acidity taking the lead over garlic. It moves quickly on the palate, cutting through grilled prawns and fried fish without lingering heaviness. Outside Thailand, “sriracha” is the preferred spelling, synonymous with a thicker, garlicky American interpretation that emphasised sweetness and body. The American sriracha may dominate shelves, but Thai si racha remains a restrained, tableside sauce—meant to sharpen food, not announce itself.
