Method:

1. Take 150ml of water and pour it in a jug. Warm up the water to around 43°C (you don’t need a thermometer, just heat 50 ml of water in the kettle and mix it with the remaining 100 ml). Add the yeast and 5 grams of caster sugar, give it a good stir then let it sit for 5-10 minutes or until foam appears on the surface.
2. Put flour, oil, salt and the remaining 5 grams of sugar in a big bowl. Start adding the yeast mixture stirring with a wooden spoon. Continue to mix and pour the rest of the water.
3. Once the dough looks sticky transfer it on a floured surface and knead it with your hands until smooth.
4. Shape it into a ball and transfer into a slightly oiled bowl. Cover with a damp towel and let it rise for about 30 minutes.
5. Grease a 35cmx25cm tin with extra virgin olive oil and transfer the dough to it. Stretch it gently to fill the tin. Cover and let it rise for another 30-40 minutes or until doubled.
6. Heat the oven to 220°C/200°C fan/gas 7. Use your fingers to poke deep dimples in the dough.
7. Drizzle with about 20 grams of oil, arrange the cherry tomatoes and about 10 olives into the dimples, sprinkle with the flaky salt and rosemary.
8. Bake for about 20 minutes, until golden. Serve warm cut into squares.
