Put the flour in a plate and mix well with the eggs and salt.
To deep-fry, add about 1 cm of oil to a large pan and heat. It is sufficiently hot if a bread cube browns in it immediately.
Turn a few eggplant slices in the egg mixture and add to the oil. They must not overlap or touch each other. Fry the slices until crispy, turning them once. Place on kitchen paper to drain. Do this until all the aubergine slices are fried.
