Cut the eggplant into slices without peeling. Drizzle with lemon juice and sprinkle generously with salt. Let it steep for 15 minutes. Rinse the slices and pat dry.
Roll in sugar, press down a little so that a lot of sugar sticks to it. Fry in hot oil on both sides until golden.
Sauté the garlic finely chopped in the frying oil for 2 minutes and pour over the aubergine slices.
