Slice and salt the eggplant
30 minUse a vegetable peeler to peel the eggplants lengthwise in alternating strips; the bands of skin left on each strip help keep it from splitting when wrapped. Slice lengthwise into 5 mm-thick strips; 4 eggplants yield 12 sturdy strips. Set aside the thin, narrow end pieces for the sauce. Layer the slices in a colander, sprinkling 15 g salt between the layers, and let them sit for 20 minutes. The salt draws out moisture, making the slices bend instead of break.
