In a large mixing bowl, add the bread flour, yeast, salt and rosemary. Make sure to add the salt and yeast on opposite sides of the bowl, then stir together
Add the water and olive oil to the flour mixture and bring it together into a dough
Knead by hand, or use a food mixer with the dough hook attachment, for 10 minutes
Put the kneaded dough into an oiled bowl covered with cling film, leave it in a warm place to rise for 1 hour
Knock the air out of the risen dough, then press it out onto a lipped baking tray. I used a Wilton Non-Stick Cookie Pan which is 33.7 x 23.5 cm (13.25 x 9.25 inches)
Press the cherry tomatoes into the dough, spacing them evenly apart
Cover with loose oiled cling film and a tea towel and leave to rise again for 1 hour
Pre-heat your oven to 200C Fan/425F/Gas Mark 7
Before baking, sprinkled more fresh rosemary, and some coarse sea salt over the dough. Bake for 20-25 minutes until golden
Allow to cool, slice and serve, or serve warm. Store any leftovers in an airtight container for up to 2 days. It also freezes well
