Now, divide the dough into 12 pieces, roll each into a ball, and then flatten it into 10 cm (4″) patty, 2.5 cm (1″) thick.
Next, use a cake wire to slice the rusk horizontally, without separating the two halves.
Place the rusks onto a baking tray, brush them with olive oil, and wrap them with cling film.
Allow proving in a warm place for a further 30 minutes.
Bake the rusks at 180°C (355°F) in static mode for one hour.
When they're cool enough to handle, cut them in half where you have previously scored them.
Finally, bake the rusks at 120°C (250°F) for 2 more hours.
