Grease a baking tray with olive oil. We want a deep pan, at least an inch deep.
In a bowl or jug, whisk together yeast, honey, and water.
In a large bowl, whisk together flour and salt.
Add the yeast mixture and use a wooden spoon or spatula to mix until you have a shaggy dough. Don't worry if it looks a bit rough, it will come together.
In a separate bowl, add 3 tablespoons of olive oil. Transfer the dough and coat it in the oil.
Now for the fun part! Oil your hands and perform the fold technique: grab one edge of the dough, stretch it gently, and fold it over the center. Repeat on all four sides, turning the bowl a quarter turn each time. Do this three to four times in total. Imagine giving your dough a series of gentle folds.
Cover the bowl and let it rise overnight in the fridge (or 4 hours at room temperature). Patience is key here – the longer rise gives the dough its wonderful flavor and texture.
Next day, take out the dough from the refrigerator. Add the remaining tablespoon of oil to your prepared baking tray. Do the folding step once again to the dough. Gently tip the dough out and spread it to fill the pan. Cover and let it rise for another hour. The dough will puff up beautifully!
Preheat your oven to 220°C
To test if your dough is ready, gently press a finger into it. If the indentation comes back slowly but leaves a slight dent, it's ready to bake.
Oil your fingers again and gently press them into the dough to create dimples, reaching the bottom of the pan. This is what gives focaccia its signature look!
Drizzle some more olive oil on top, sprinkle some salt flakes and also top with some fresh rosemary.
Bake for 20-25 minutes, or until golden brown. The focaccia will be fragrant and irresistible!
Let the focaccia cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. Resist the urge to dig in right away – letting it cool slightly allows the flavors to develop further.
Enjoy!
