Thai Rice Varieties and Their Cooking Uses
Explore Thai rice varieties by sight, touch, aroma, and taste. Learn what kind of rice is sticky, how to cook jasmine and glutinous rice, and where each type shines in Thai dishes.
Contents
Thai rice is not just a side dish—it is the heart of the meal. The main types you will encounter are jasmine rice (fragrant long-grain), glutinous rice (often called sticky rice), and black sticky rice (a whole-grain dessert rice). Jasmine rice is fluffy and aromatic, perfect for curries and stir-fries. Glutinous rice is chewy and clumps together, ideal for eating with your hands and soaking up bold flavours. Black sticky rice has a nutty, slightly sweet taste and is used mainly in desserts.
What Kind of Rice Is Sticky?
Sticky rice is glutinous rice—a specific type of rice with a high proportion of amylopectin starch and very little amylose. This makes the grains cling together firmly when steamed. Despite the name, it contains no gluten. In Thailand, it is called khao niao. The cooked texture is dense, chewy, and slightly translucent. It is traditionally eaten with the hands: you pinch off a small ball, flatten it, and use it to scoop up bites of grilled meat, spicy salad, or dipping sauce.
Sticky rice is not interchangeable with jasmine rice. Jasmine rice, with more amylose, cooks into separate, fluffy grains. If you try to make sticky rice from jasmine rice, it will not hold together for hand-eating. Conversely, glutinous rice is too sticky for dishes where you want loose grains.
Types of Thai Rice: A Closer Look
Jasmine Rice (Khao Hom Mali)
Jasmine rice is a long-grain rice with a delicate floral aroma, often compared to pandan or popcorn. The raw grains are slender, pearly white, and slightly translucent. When cooked, the grains elongate further, remain separate, and have a soft, slightly clingy texture that is less dry than other long-grain rices like basmati. Its subtle fragrance and gentle flavour make it the default rice for most Thai meals, from green curry to pad kra pao.
Cooking tip: Rinse jasmine rice in cold water until the water runs almost clear, then use a 1:1.25 rice-to-water ratio by volume. Simmer covered for about 12–15 minutes, then rest off heat for 10 minutes to let the grains set.
Glutinous Rice (Sticky Rice)
Glutinous rice grains are short, plump, and opaque white when raw, resembling tiny pearls. When cooked, they become translucent, extremely sticky, and glossy. The texture is chewy with a slight bounce. Its flavour is neutral but slightly sweet, making it a perfect canvas for strong flavours.
The traditional cooking method is steaming, not boiling. First, soak the rice in water for at least 4 hours (or overnight). Drain, then place in a bamboo steamer basket lined with cheesecloth or a banana leaf. Steam over boiling water for 20–30 minutes, flipping the rice halfway. Steaming ensures each grain cooks evenly and becomes fully sticky without becoming mushy.
Common dishes: Sticky rice is essential with som tam (green papaya salad), larb (minced meat salad), and grilled chicken (gai yang). It is also the base for the famous Thai dessert khao niao mamuang (mango sticky rice).
Black Sticky Rice (Khao Niao Dam)
Black sticky rice is a whole-grain glutinous rice with a deep purple-black bran layer. Raw grains are opaque black; when cooked, they turn a rich, shiny aubergine purple. The texture is chewier than white sticky rice, with a pleasant pop from the bran. Its flavour is nutty, earthy, and subtly sweet, with a hint of toasted grains. It is not eaten as a savoury staple but is used in desserts, often mixed with white glutinous rice for contrast and served with coconut milk and fresh fruit.
Preparation: Black sticky rice needs a longer soak (at least 6–8 hours) and longer steaming (45–60 minutes) than white sticky rice. If you want a softer texture, you can simmer it in water like porridge for desserts such as khao niao dam sangkaya (black sticky rice with custard).

How Rice Shapes a Thai Meal
In Thailand, rice is the anchor that balances intense flavours: spicy, sour, salty, and sweet. Jasmine rice offers a fragrant, neutral cushion for rich coconut curries. Sticky rice provides a chewy, hand-held tool for scooping up sharp, herbaceous salads. Black sticky rice turns dessert into a celebration of texture and deep colour. Understanding these differences helps you choose the right rice and appreciate why a dish is served the way it is.
Simple Substitutions and Their Limits
- No jasmine rice? Any soft, aromatic long-grain rice like basmati can work, but expect a less floral aroma and slightly drier texture. Avoid using medium-grain rice, which can become too sticky.
- No glutinous rice? There is no true substitute for sticky rice texture. Sushi rice is stickier than jasmine but still not the same; it lacks the dense, bouncy chew and cannot be formed into the same firm balls. If you only need a sticky base for dessert, sushi rice can hold together but will be softer.
- Can I cook sticky rice in a pot? You can, but steaming is far superior. If you must, soak the rice, then use a 1:1 ratio of water to rice in a heavy pot, cover tightly, and cook on the lowest heat for 15–20 minutes. The result will be stickier than jasmine but not as evenly cooked as steamed sticky rice.
With a little practice, you can recognise these rice varieties by sight and touch, and use them to bring an authentic Thai meal to your own table.
