• Try to vary the meat and vegetables in a dish, so that there is an interesting variety of flavors, textures, and colors. The Chinese believe it is important to find balance and harmony in every aspect of life, including food.
   
• Fresh is best: always use fresh ingredients when possible.
   
• Be sure to have everything prepared before you start cooking: the vegetables washed, drained and cut; the meat cut and marinated; the sauces prepared.

2. Chinese Cooking Equipment: 

• While you don't absolutely need one, a wok is the one piece of cooking equipment you may want to purchase before you start cooking Chinese food.
• While it's nice to own one, you don't need a cleaver to cook Chinese food.

3. Preparing Vegetables: 

• Wash green, leafy vegetables ahead of time. This gives them more time to drain so they will not be too wet when you stir-fry.
   
• Place all the cut vegetables on a tray or cooking sheet. That way, you won't forget anything. Just be careful not to mix them up, as cooking times will vary among vegetables.

• When stir-frying vegetables, cook the toughest and thickest vegetables for a longer period than the softer, leafy vegetables. Vegetables such as broccoli, carrots, and cabbage need to be cooked longer than bok choy, which in turn is cooked longer than snow peas or bean sprouts.
   
• If you are uncertain in which order to cook vegetables, simply stir-fry them separately. Never overcook.

5. Tofu (Bean Curd): 

• For stir-frying or deep-frying, use firm or extra-firm tofu. Firm tofu will keep its shape and not fall apart in the wok.
   
• Drain the tofu before using, as this allows it to absorb the other flavors in the dish.

6. Meat and Fish: 

• Always marinate fresh meat.
   
• Always cut beef across the grain. This helps make it more tender.
   
• Cut the meat into uniform pieces so that it will cook more evenly.
   
• When cooking meat or poultry, make sure that the wok is very hot before adding the food.
   
• If preparing stir-fried meat and vegetables, stir-fry the meat first and set it aside. Usually you will return it to the wok with a sauce during the final stages of cooking.

7. Cooking With Oil: 

• When adding oil for stir-frying, drizzle the oil down the sides of the wok.
   
• When deep-frying, to tell if the oil is hot enough, simply stick a chopstick in the wok. When the oil sizzles all around it, you can begin adding the food.

8. Sauce and Seasoning Tips: 

• Always use fresh ginger, not powdered.
   
• If desired, use sugar as a substitute for MSG (Monosodium Glutamate).
   
• The formula for mixing cornstarch and water is 1 to 2 or 1 to 4: for example, 1 tablespoon of cornstarch with 2 tablespoons of water.
   
• Don’t use more cornstarch than called for in the recipe

Finally, remember that, in the immortal words of one of my favorite cooking teachers: "the two most important things about Chinese cooking are a hot stove and a sharp knife."
