Once cooked, peel it and mash it with a potato masher. In a bowl mix the semolina flour and the 00 flour. Add the yeast, sugar, salt and the mashed potato. Add the water, beer and
Terra Gentile Extra Virgin Olive Oil and start kneading until you get a smooth and firm dough. Place the dough in a bowl covered with a damp cloth and let it rise in a warm place until it has doubled its initial volume (about 2 hours). Roll out a sheet of dough about 1 cm high on a floured pastry board and use the rim of a glass to make some focaccias. Place the focaccias on a baking sheet lined with baking paper and let them rise for another hour. Press the focaccias in the center to form the edge, add a drizzle of extra virgin olive oil and cook in a preheated static oven at 200° for 15 minutes.
Take your focaccias out of the oven and serve them while still hot accompanied by the Spalla Cotta di San Secondo and sliced Culatta ! Accompany the dish with a glass of beer !
