In a mixing bowl, stir together the flour, yeast, salt and garlic powder. Then stir in the grated cheese.
Add the water and use a wooden spoon or silicone spatula (recommended) to bring the dough together. It will seem a little dry and shaggy looking at first, but it will turn into a soft and sticky mass in just a couple of minutes.
Shape the dough into a ball (doesn't have to be perfect) and let it remain in the bowl. Cover with clingfilm and let it rest at room temperature for 2 hours, or until doubled.
Place the bowl, still covered, in the fridge overnight and up to 3 days. I usually let it chill for about 14 to 16 hours.
The next day, scrape the dough out of the bowl and place on a very lightly floured silicone baking mat. Shape the dough into a smooth ball with lightly floured fingers because the dough will still be sticky. I prefer a silicone mat here because it won't slide around as you shape the dough.
Loosely cover the dough with the same sheet of clingfilm and let it rise again for 45 minutes to 1 hour. It will puff up and spread a bit.
In the meantime, preheat the oven to 250 C.
Uncover the dough and if it looks a little misshapen, use floured fingertips to nudge it back into shape. Use a sharp knife to make two long cuts along the top, forming a + sign. This step, called 'scoring', allows the dough to expand more evenly as the bread bakes.
Slide the mat onto a baking tray and bake for 25 to 30 minutes until browned on top and the smell is just irresistible!
Let the bread cool completely at room temperature, on a wire rack. As amazing as warm bread tastes, being patient actually helps create a better texture as it continues to bake as it cools. Slice and dig in! Will keep at room temperature for a day or two in an airtight tin but in humid weather, I prefer storing it in the fridge for a week and toasting as needed. Happy baking!
