Introducing other Aromatic Herb and Spices in Thai cuisine There are some key ingredients that give Thai food it's distinctive aroma, depth and layers of flavour. Lemongrass, galangal, lime (rind and leaves), coriander leaves, sweet Thai basil leaves and garlic are used in one way or another is all Thai dishes.

Lemongrass in Thailand is called takhrai (ตะไคร้).

Fresh lemongrass is available at most large supermarkets now; otherwise, try your local Asian market to get your hands on the herb. Dried lemongrass is common, although it isn't as flavorful. Lemongrass tea is also readily available.

When shopping for fresh lemongrass, look for stalks that are green, firm, and fragrant and with outer leaves that aren't too desiccated (indicating a longer time in storage).
