Cut the eggplant into slices; layer them in a colander and place the colander in a salad bowl that can hold it.
Between each layer of eggplant sprinkle coarse salt, place a plate on the layers of eggplant and a weight on the plate.
After at least an hour, the eggplants will have lost their vegetation liquid and will be less bitter.
The tomato sauce you need for eggplant parmesan is the same as you need for a great pizza base.

Rinse the eggplants under running water to remove excess salt, squeeze them without breaking them and dry them with paper towels. In a frying pan, heat the oil (seed oil for frying) and fry the eggplants, a few at a time. Place them to dry in a dish with absorbent paper to remove excess oil.
Place a ladleful of sauce in an ovenproof pan and make a first layer of eggplant, sauce, mozzarella cut into slices or cubes and grated cheese. Continue in this manner until the pan is filled.
Finish by covering everything with the sauce and a final sprinkling of grated cheese.
