If you think American cooking means opening a package and throwing the contents into the microwave oven (微波炉), think again. On the one hand, it’s true that many Americans have cold cereal for breakfast, sandwiches for lunch and instant (方便的) dinners. From busy homemakers to working people, many Americans enjoy the convenience (方便) of fast food that can be ready to serve in 10 minutes or less. On the other hand, many Americans realize the importance of cooking skills. Parents — especially mothers — see the importance of training their children — especially daughters. Most Americans think that there’s nothing better than a good home-cooked meal. But with cooking, as with any other skill, good results don’t happen by accident.

Probably every cook has his or her own way of cooking. But there are some basic skills that most people follow. For example, baking is a main method (方法) of preparing food in America. For that reason, Americans would find it next to impossible to live without an oven. American cooks pay special attention to the balance of foods, too. In planning a big meal they try to include meat, a few vegetables, some bread and often a dessert. They also like to make sure the meal is colorful. Having several different colors of food on the plate usually makes for a healthy meal.

For those who need guidance in their cooking, or for those who have just run out of ideas, recipes are a great help. Recipes list all the ingredients for a dish (generally in the order used), the amount of each to use, and a description of how to put them together.
