Steps
To prepare the Genoese focaccia, pour the Manitoba flour and 00 flour into a bowl. Mixed with a spatula, then make a slight hole in the center and pour almost all the water. Stir again to let the water absorb, then add the malt and the salt all together. Stir, then pour in the remaining water and work again with the spatula until you get a homogeneous paste. Once the salt has integrated into the flour, you can add the crumbled brewer's yeast.
A few more rounds of spatula and the dough is ready to transfer it to the work surface and continue to work by hand, rather vigorously. If there is a little unabsorbed flour left, it does not matter: it will be absorbed by working it, applying pressure with the palm of your hand while kneading, just to "tear the dough" by replicating the movement of the machine. After a few minutes, when you see that the gluten mesh takes shape, so the dough is more homogenous and almost elastic.
Pour the oil on the dough and continue to work on the surface to absorb all the oil while kneading vigorously. Depending on the type of flour used, while working, it may be necessary to sprinkle with very little flour. In all it will take 13-15 minutes, to obtain a smooth and homogeneous mixture. You can cover it and let it rest for a few minutes.
Remove the tea towel and close the dough by rolling it on the surface, you will notice that in a few seconds it will become smooth. Divide the dough into two 500 g pieces, give a rectangular shape by crushing it with your hands and give it a three-fold. To do this, you can fold the dough on itself, bringing a flap inwards and then folding again, leaving a line underneath and rolling it to finish, so that the closure remains in contact with the workbench, lightly dusted with flour. Repeat the same operation for the other half of the dough. Cover with a cloth and let it rest for about 30 minutes.
Remove the tea towel, take one of the two loaves and keep the other covered. Grease the first 30x40 pan with 15 g of oil, without going into the corners because it will go there alone. Place the dough on a floured surface, press it with your fingers to spread it out, always using only the index, middle and ring fingers then 3 fingers of the hand. Then move on to rolling out the dough with a rolling pin, turning the dough from time to time in order to maintain a rectangular shape. Pass your hands under the dough, then turn them so that the backs of your hands lift the dough to lay it without damaging the dough on the pan until it covers 70-80%. Cover with a cloth and let it rest for another 20-30 minutes. In the meantime, repeat the same operation for the second loaf of dough
Sprinkle the focaccia with a little flour, mash well with your fingertips, spreading the dough all over the pan, starting from the perimeter to create a small edge. It is important that the dough adheres well to the pan, in this way when you pour over the brine, it will not end up on the bottom. Smooth the surface as much as possible with the palms of your hands. Cover again and let it rest for an hour.
Prepare the brine by mixing water and salt together, until it is well dissolved. Uncover the focaccia, sprinkle it with very little flour and with the three fingers (index, middle ring finger) impress the typical holes by making a good pressure and pushing towards the edges: the fingers must not be perpendicular to the dough, but slightly inclined. You will have to leave about 1 cm between one hole and another. When you have almost finished making all the holes, turn the pan, in this way it will be easier to make all the holes even along the remaining edge
Now pour 30 g of oil and 90 g of brine into the center of each focaccia. Then spread it gently with your hand to fill all the holes. Let it rise for another 40-45 minutes, this time without covering it. Bake in a static oven preheated to 230 ° for 15 minutes (if the oven is very powerful, we recommend changing the timing, but not the temperature for your oven). When the surface is golden, you can take out your focaccia! Let it cool for a few minutes, cut it and serve it!
