Place the water and yeast into the Thermomix bowl. Mix for two minutes at 37 degrees on speed 1.
Add the olive oil, plain flour and salt and mix for 8 seconds on speed 6. Scrape down the sides of the bowl and mix on Interval (knead) function for 2 minutes.
Place the mixture into a greased bowl (or ThermoServer) and leave in a warm place to rise until doubled in size (approximately 1 hour).
Preheat oven to 200 degrees celsius (fan-forced). Line a large flat baking tray with baking paper and set aside.
Punch the dough down and then spread onto the prepared baking tray. Use the end of a wooden spoon to indent the dough.
Press the olives and rosemary leaves lightly into the mixture. Allow to prove for a further 15 - 30 minutes.
Sprinkle with extra sea salt and bake for 25-30 minutes or until golden.
Notes
Plain flour can be used instead of Baker's Flour
You can add 1 tablespoon of bread improver for a lighter consistency.
The time it takes for the dough to double in size will depend on the climate.
The baked focaccia can be frozen for up to two months.
Add your toppings before baking and gently press them into the dough.
