Step 1

Lightly oil a 2–3 litre square plastic container. (Make sure you use a square tub as it helps shape the dough.)

Step 2

Tip the flour into a large mixing bowl and add the yeast to one side of the bowl and the salt to the other.

Step 3

Add three-quarters of the water and 40ml of olive oil, and turn the mixture round with your fingers. Continue to add water, a little at a time, until you’ve picked up all the flour from the sides of the bowl. You may not need to add all the water, or you may need to add a little more. You want your dough to be very soft – wetter than a standard bread dough. Use the mixture to clean the inside of the bowl and keep going until the mixture forms a rough dough.

Step 4

Coat the work surface with some of the remaining olive oil, then tip the dough onto it and begin to knead. Knead for around 5–10 minutes. Work through the initial wet stage until the dough starts to form a soft, smooth skin. (It’s best to avoid adding any more flour as it is supposed to have a wet, sticky consistency.)

Step 5

When your dough feels soft and elastic, put the dough into the oiled tub. Cover with a tea towel and leave to rise until at least doubled in size – about 1 hour.

Step 6

Line 2 baking trays with baking parchment and drizzle with olive oil.

Step 7

Put more olive oil on the work surface and dust with fine semolina if you have some. Carefully tip the dough onto the surface. Handle the dough very gently so you keep as much air in it as possible. Divide the dough in half. Stretch each piece out to a flat, even piece and place on a baking tray.

Step 8

Put each tray into a clean plastic bag and leave to prove for about 1 hour, until the dough is doubled in size and springs back quickly if you prod it lightly with your finger.

Step 9

Meanwhile, heat your oven to 220˚C/425˚F/Gas Mark 7.

Step 10

Use your fingers to make deep dimples in the focaccia, pushing them all the way through the dough to the bottom. Drizzle each focaccia with olive oil and sprinkle with a little flaky sea salt and oregano, then bake for 15 minutes, or until cooked through.

Step 11

Tap the bottom of the focaccia and you should hear a hollow sound. Trickle with more olive oil, then cool on a wire rack.
