Nowadays, many dishes in hotels use food additives, which I personally disapprove of, but hotels often acquiesce in the pursuit of selling vegetables. I have a small method that you can try. Cut the eggplant into strips first, and then put it in the microwave oven 15 minutes or so until it becomes soft. After taking it out, take it out and fry it with dry starch. After frying, it will feel crisp when it is almost cooked.
