Bamboo Shoots: Bamboo shoots are called for in many Thai recipes. In order to prepare a bamboo shoot for cooking you need to peel them and boil the white inner stalks for 30 minutes in water. If you are using canned bamboo shoots you will only need to boil them for 10 minutes, or if they are going into curries or soups, boiling might not be required.
Basil (fresh): There are three types of basils used in Thai cooking; sweet, holy and lemon. Sweet basil is much easier to find because it is commonly used in western cooking. Holy basil has a spicier taste and can be recognized by it’s slightly purple leaves. Lemon basil has a lemony flavor and can be detected by its distinct lemony scent. If you can only find sweet basil you can compensate for holy or lemon basil by adding finely chopped chili peppers or a bit of lemon rind.
Bergamot: Also known as kaffir lime leaves has a slightly limey flavor which goes well with all Thai dishes. Since this may be hard to find, granted lime rind can be used in its place although it is a poor substitute.
Chili paste: This can be bought in bottles or tubes in almost any supermarket. Used for adding spice and flavor to most dishes, a particularly popular version by Thai cooks is burnt mild chili paste.
Chinese mushrooms: Mushrooms are added to a lot of Thai cooking and many people chose to use the dried variety because they are cheaper and have just as much flavor and nutritional value. You will need to soak the mushrooms in warm water for 30 minutes before using them and the stems are usually discarded because of their tough nature.
Coconut milk: Coconut milk can be bought in cans almost anywhere. If the recipe you are using calls for coconut cream scoop the harder white substance that has formed at the top of the can. If you need coconut milk, stir the can thoroughly before using.
Curry Paste: While some people prefer to prepare their own curry pastes, many bottled curries are available at the supermarket. Most recipes use red, green or yellow curry.
Fish sauce: Made from collecting the liquid off of fermenting salted fish, this pale, watery brown sauce is sometimes used to replace all the salt in recipes. It is very flavorful and compliments all Thai food. It is called for in many recipes but you can also use your imagination with it, as it is very versatile.
Galangal: A close relative to ginger, is used in many curries and soups. Since it is quite rare to find fresh you will probably have to purchase it dry and soak it in water for 1 hour before using.
Garlic: Thai garlic might be available in some Asian markets, however if you cannot find it, the Western variety will work just as well. Use the smaller, tighter cloves on your garlic head for Thai cooking because they are more flavorful and will not be over powered by the other herbs and spices used in your dish.
Ginger: Easy to find and used quite often in modern cooking, ginger is extremely healthy and flavorful. It must be peeled before it is grated or chopped. Fresh ginger is much better than dried, although dried may be substituted if needed.
Lemon grass: Lemon grass is one of the most commonly used items in Thai cooking. It is a long stalk that looks like a small leek. The hard outer portion should be removed and the lower, bulbous part is used. You can either add sliced pieces to your food while it is cooking and remove them before serving your dish, or you can blend them in a food processor so they can be consumed with the dish, which will give it more flavor.
Palm Sugar: Some Thai recipes call for palm sugar which is available in some Asian markets as cellophane wrapped blocks. If palm sugar is unavailable you can substitute with dark brown sugar or real maple syrup.
Rice: Thai people prefer long-grain white Jasmine rice. This is a flavorful and aromatic rice that cools and compliments spicy Thai dishes.
Rice papers: Used for making fresh Thai spring rolls, you can buy rice papers at any food store. To use soak papers (one at a time) in warmish water until they are soft and pliable, then dry off with paper towel and use immediately.
Sesame Oil: A vegetable oil that comes from pressed sesame seeds and originated in East India. This is a very flavorful oil and works very well with Thai cooking.
Preparation and cooking techniques:
Vegetables: Vegetables used in Thai cooking should be cut as finely as possible. The idea is that the smaller they are chopped, the less time they will need to be cook, therefore retaining as much nutrients as possible.
Stir frying: Most people have cooked a stir fry before, so will be familiar with this method of cooking. Oil should be poured into a wok and vegetables should be added over high heat while being constantly stirred. Vegetables should only be stir fried for a couple of seconds so they remain crisp and brightly colored.
Mortar and Pestles: Perfect for making sauces, curry pastes and salads, every Thai cook should own a mortar and pestle preferably made out of clay or wood.
Mincing: Since Thai cooking uses so many intensely flavorful ingredients they should all be chopped very finely so one flavor never overpowers the other. You should always use a very sharp knife for this.
Roasting and grinding spices: When adding spices and herbs to your Thai dish you should always roast them by slowly heating each spice individually in pan until they begin to crackle and turn brown. When each spice is done roasting they should be ground very finely in a food processor or mortar.
