Red onion and olive focaccia

1.Preheat oven to 220C. Combine yeast and 225ml lukewarm water in a bowl and stand until foamy (3-5 minutes). Combine flour, olive oil and 1 tsp sea salt in a bowl. Add yeast mixture and mix thoroughly with your hands to combine. Turn onto a lightly floured surface and knead until smooth (4-6 minutes). You may need to dust with extra flour if dough is too sticky. Transfer dough to a lightly oiled bowl, cover with a damp tea towel and stand in a warm place until doubled in size (35-40 minutes).

2.Meanwhile, bring wine and sugar to the boil in a small saucepan. Add onion and cook over medium heat until onion is soft (5-10 minutes). Cool and drain well (discard liquid).

3.Knock back dough and knead until smooth (1 minute), roll to 5mm thick on a floured work surface and transfer to a baking paper-lined oven tray. Scatter with red onion, olives, oregano and sea salt, drizzle with olive oil and bake until golden and puffed (25-30 minutes). Serve warm or at room temperature.
