A number of different styles contribute to Chinese cuisine. These styles are distinctive from one another due to factors such as availability of resources, climate, geography, history, cooking techniques and lifestyle. One style may favor the use of lots of garlic and shallots over lots of chili and spices, while another may favor preparing seafood over other meats and fowl.
Based on the raw materials and ingredients used, the method of preparation and cultural differences, a variety of foods with different flavors and textures are prepared in different regions of the country. Many traditional regional cuisines rely on basic methods of preservation such as drying, salting, pickling and fermentation.
CANTONESE FOOD
Guangdong has long been a trading port and many imported foods and ingredients are used in Cantonese cuisine. Besides pork, beef and chicken, Cantonese cuisine incorporates almost all edible meats, including offal, chicken feet, duck's tongue, snakes, and snails. However, lamb and goat are rarely eaten, unlike in the cuisines of northern or western China. Many cooking methods are used, with steaming and stir frying being the most favoured due to their convenience and rapidity. Other techniques include shallow frying, double steaming, braising, and deep frying.
For many traditional Cantonese cooks, the flavours of a finished dish should be well balanced and not greasy. Apart from that, spices should be used in modest amounts to avoid overwhelming the flavours of the primary ingredients, and these ingredients in turn should be at the peak of their freshness and quality. There is no widespread use of fresh herbs in Cantonese cooking. Garlic chives and coriander leaves are notable exceptions, although the latter are usually used as mere garnish in most dishes.
SZECHUAN FOOD
Szechuan cuisine often contains food preserved through pickling, salting, and drying and is generally spicy owing to heavy application of chili oil. The Sichuan pepper is commonly used. Sichuan pepper has an intensely fragrant, citrus-like flavour and produces a numb sensation in the mouth. Also common are garlic, chili peppers, ginger, star anise and other spicy herbs, plants and spices. Broad bean chili paste is also a staple seasoning in Szechuan cuisine. The region's cuisine has also been the source of several prominent sauces widely used in Chinese cuisine in general today.
Common preparation techniques in Szechuan cuisine include stir frying, steaming and braising, but a complete list would include more than 20 distinct techniques. Beef is somewhat more common in Szechuan cuisine than it is in other Chinese cuisines, perhaps due to the prevalence of oxen in the region. Stir-fried beef is often cooked until chewy, while steamed beef is sometimes coated with rice flour to produce a very rich gravy.
FUJIAN FOOD
Fujian cuisine is one of the native Chinese cuisines derived from the native cooking style of Fujian province, China. Fujian-style cuisine is known to be light but flavourful, soft, and tender, with particular emphasis on taste, as well as retaining the original flavour of the main ingredients instead of masking them.
Many diverse seafoods and woodland delicacies are used, including a myriad of fish, shellfish and turtles, or such edible mushrooms and bamboo shoots, provided by the coastal and mountainous regions of Fujian. The most commonly employed cooking techniques in the region's cuisine include braising, stewing, steaming and boiling.
Particular attention is paid on the finesse of knife skills and cooking technique of the chefs, which is used to enhance the flavour, aroma and texture of seafood and other foods. Strong emphasis is put on the making and utilising of broth and soups.
Fermented fish sauce, known locally as "shrimp oil", is also commonly used in the cuisine, along with oysters, crab, and prawns. Peanuts are also prevalent, and can be boiled, fried, roasted, crushed, ground or even turned into a paste. Peanuts can be used as a garnish, feature in soups and even be added to braised or stir-fried dishes.
