Step 1

Mixing The DoughWeigh out your sourdough starter and water into a large bowl.Mix the water and starter together briefly. Then add flour and salt and mix whole lot together until it forms a sticky dough. You don't want any dry flour left at all.You can use a dough scraper or Danish dough whisk for this process.

Step 2

Cover your bowl with cling film or a damp tea towel and let it sit for around 1 hour. It's ok if it's a little bit longer, it's not going to matter too much.

Step 3

Strengthening the DoughAfter the dough has been through autolyse you need to bring it together into a ball. Work your way around the bowl, grabbing the dough from the outside, stretching it up and over itself, into the centre. You should feel the dough strengthen as you do this. It doesn't have to be perfectly smooth or tight, just work around the bowl stretching and folding (around 10 - 15 times is perfect).

Step 4

Bulk Ferment:Now you want to leave your dough to ferment. Cover it with a tea towel or plastic wrap and leave it alone to double (see notes).Focaccia is super forgiving so it doesn't need to be perfectly doubled - near enough is fine.

Step 5

Shaping Focaccia:Once the dough has doubled you need to shape the dough. Shaping focaccia is super simple (and absolutely forgiving). See my notes in the post above for details on baking pans/dishes.Use a dough scraper to gently ease the dough out into your desired pan.

Step 6

Rub your hands with a little olive oil and gently pull the dough out to fill the tray. Again it doesn't have to be perfect as it will naturally fill the tray as it proofs.

Step 7

Second Rise:Let your dough rise again. Leave it until it's spread out and filled the tray. It will be puffy and pillowy ... you might even have some gorgeous bubbles popping up.

Step 8

Topping:Once the dough has filled the tray and is looking puffy and full of volume, you need to dimple the dough and add the toppings.Pour olive oil over the top of the dough and then push your finger tips into the dough to create dimples. You might see some bubbles as you do this.Now sprinkle with sea salt and rosemary.

Step 9

Baking Sourdough Focaccia:Preheat the oven to 200C (392F).Bake for 30 minutes or until golden brown.
