Knead the dough for 5-10 minutes until it is soft, smooth and not sticky. Place the dough into a separate, clean bowl and cover it with a tea towel before leaving it to rise in a warm place.
Using your hands, press the dough into a flat shape right into the sides and corners of the tray. It will attempt to spring back, so be firm and eventually, it will listen.
Take it out of the oven and drizzle over more olive or truffle oil and sprinkle over more salt, before slicing it up and serving still warm from the oven.
