In a large bowl, mix the yeast, warm water and sugar. Let it sit for about 5-10 minutes until foamy.
Add the flour, a little at a time while mixing with a wooden spoon. When about half the flour has been mixed in, stir in the salt. Then continue adding in the rest of the flour.
Mix well until all the flour has been incorporated and you have a shaggy dough. Cover the bowl with plastic wrap and let sit at room temperature for about 30 minutes.
With wet hands, take the top of the dough. Stretch and fold it over to the middle of the dough. Repeat for the 3 other sides of the dough.
Flip the dough upside down so all those folds are facing the bottom. Cover with plastic wrap and let sit for 30 minutes. Repeat these "folds and flip" another 3 times with the 30 minute rest in between.
After the last folds, flip the dough upside down but this time in an oiled bowl. Cover with plastic wrap tightly and place in the refrigerator. Let rise overnight - at least 12 hours. Even longer would be better (up to 24 hours to develop the most flavor).
Preheat the oven to 260°C (500°F).
Line an 13x9 inch pan with parchment paper, and oil it generously - even up the sides of the pan.
Let the dough fall on it's own from the bowl, helping it as little as possible (try to preserve the air that has developed inside as much as possible).
Wet your hands and lightly stretch the dough to fill the entire pan. If needed let the dough sit in room temperature for a few minutes before stretching.
Cover with a dish towel and let sit for 30 minutes. This time I place the dough on top of the preheating oven, just to give it some warmth to help with the rising.
Now it's time to gently make the classic indentations in the dough with your fingers. Add any toppings you want! Some suggestions: halved cherry tomatoes, rosemary, oregano and flaky salt. Or make it sweet: sprinkle some cinnamon and sugar.
Whisk the tbsp of water, olive oil and tsp of salt. Drizzle over the entire dough.
Bake for about 15-20 minutes, or until the top and bottom is golden brown.
Let cool completely and serve.
