I wouldn't recommend making the eggplant fries blossom ahead of time. It is best when you make it fresh because it tends to get soggy. You can create the dredging mixture ahead of time and you can cut the eggplant a short time ahead, but I would wait to fry the eggplant until you are ready to serve it. While it is edible when reheated, this is a dish best served piping hot and fresh from the fryer. The longer it sits, the more likely it will get soggy. This would result in an unpleasant texture.
