I think, first of all, we should choose high-quality oil, and it is best to buy brand-name oil. As for the ingredients, it's not a big problem, just vegetable oil. It is best to use corn oil or olive oil, because these oils are fresher than peanut oil and soybean oil.

Then fry as soon as possible. Many things feel greasy after frying because of its own material, such as eggplant. The chef will try to shorten the frying time because it will absorb oil. Of course, everything absorbs oil, but to different degrees. Therefore, please try to shorten the frying time.

Then you can wrap some flour or starch when frying, which is not only crisp and delicious, but also prevents oil from infiltrating.

Finally, it is suggested to drink some tea when eating fried food, which can relieve the greasy feeling and make you feel comfortable after eating.

Hehe, the above is my own experience. If there is any mistake, please include it.
