Modern times have blurred some of the regional lines, and it is now not unusual to find specialties from one area prepared in all parts of the country. But the traditions of each area endure, so that a devotee of Chinese cooking is always aware of a dish's origin-and the flavors, ingredients, and techniques that go with it. Because of that, it helps to understand the four primary regions, or schools, of Chinese cooking: The Northern, Eastern, Western, and Southern schools.

Most classic Chinese cuisine is inherently healthful because of its reliance on vegetables, vegetable oils, stir-frying, and fat-free condiments. But sodium levels can get pretty high because many condiments such as soy, oyster, and hoisin sauces are higher in sodium. Our solution? Low-sodium soy sauce. We also kept the fat down by using less vegetable oil than traditional recipes call for.

Here's more information on the origins of Chinese cuisine, and recipes for some of its signature dishes.

The Northern School includes Beijing, the northern provinces, and Inner Mongolia. Its cuisine is the most eclectic, incorporating the refined cooking of palace kitchens and Shandong province (where classic Chinese cuisine originated), as well as Mongolian and Muslim dishes.
