Take around a cup full of the warm water from the above recipe and sprinkle in the dried yeast, (you can add a little sugar to help the yeast, approx. half teaspoon), cover over and leave in a warm place for around 10 to 15 minutes. You should see a little foam on top, it's now ready to be used.
Place all the ingredients into a mixing bowl and mix with a dough hook for around 10 to 12 minutes on slow speed, or mix vigorously by hand for a similar amount of time (or as long as you can keep going!).
Generously drizzle Extra Virgin Olive Oil to cover the sides and bottom of a bowl at least double the size of the dough piece. Place the dough in the bowl and cover over with a damp tea towel or clingfilm. Leave for at least 1 hour in a warm place until it roughly doubles in size until it nearly touches the cover - don't worry if it takes half an hour longer, it's all adding to a great taste and texture!
Remove from the bowl onto a lightly floured surface and 'knock the dough back' - work it for around 30 seconds. Split the dough into two equal sized pieces and shape into a rough ball. Cover over and leave it to relax for about 10 minutes while you prepare your baking tins.
Drizzle a generous amount of Extra Virgin Olive Oil into your baking pan ensuring the whole of the bottom and sides are covered. The pans need to be somewhere around 30cm long and 20 cm wide (12 x 8 inches) and about 6cm deep (2 and A half to 3 inches). The pan can be a bit smaller, but the Focaccia will end up deeper and taller.
Pour some Extra Virgin olive onto your work surface and on the dough, then press it out to roughly the size of the tin. Place in the tin and tease out to the sides being careful to try to keep an even thickness overall.
Cover the tin with a damp tea towel or cling film and place in a warm place and leave to rise. This will take at least 45 minutes and could take up to an hour and a half depending on room temperature. The dough should roughly double in size. Tip - when the dough is fully proved, if you press with your finger it will leave an indent and not spring back.
Remove the film / cloth. Dip your fingers in olive oil then press your fingers in at around 1 inch spacings, then a good drizzle again with Extra Virgin olive oil.
Garnish the top of the dough with whatever takes your fancy - olives, cherry tomatoes, sprigs of rosemary, sea salt, coarse ground black pepper, grated Parmesan, Parma ham, dried Tuscan herbs, fresh herbs, garlic, infused oils, artichokes, caramelised onions, sautéed mushrooms or anything else you fancy from the fridge.
Place in the middle of a pre-heated oven at 210c / 410f / gas mark 6. Reduce temperature by around 10 degrees if using a fan oven. Bake for around 15 to 20 minutes until golden brown on top. Check underneath to make sure its golden brown on the bottom, give an extra 3 or 4 minutes if necessary. And enjoy!
