Cooking always lacks a bit of flavor do not know how to do

I think it is at the beginning of the frying pan when the oil is not fried, like thirteen spices do not necessarily put, some dishes must be first to the soy sauce frying, onion is also necessary to put some garlic together with the frying, such as hot and sour potatoes on the must have garlic to have that kind of flavor. Personally, I think the most important thing in the beginning of the frying pan is the same as the marinade made by the great chef, flavorful enough. I hope it can help you some.
