Mix the bread blend with yeast. Add water, then oil and salt. Mix for 5 minutes to form a soft, sticky dough.
Spread in an oiled, lined tray with wet or oiled hands. Cover and leave to rise until noticeably puffy, about 60–90 minutes depending on temperature.
Heat a conventional oven to 220 °C. Mix topping oil and water. Dimple the dough gently with oiled fingertips and spoon over the topping. Add rosemary.
Bake for 25–35 minutes until golden and set. Cool on a rack before slicing.
