• STEP 1

    Mix the flours with the yeast and salt, add 1 tbsp oil, then pour in 320ml lukewarm water and mix well. You want a very soft dough – don’t worry if it looks a little wet, this will make a lighter focaccia. Knead for 5 mins if using a stand mixer, or 10 mins by hand, using a dough scraper if you have one and lightly oiling your hands and the surface. Transfer the dough to a lightly oiled bowl, cover with a damp tea towel and leave to rise until it has doubled in size.

  • STEP 2

    Meanwhile, melt the butter in a large frying pan with the remaining oil, add the onions and a pinch of salt, and cook gently for 20 mins or until very soft. Pour in the vinegar and cook for a further 10 mins until sticky. Set aside to cool.

  • STEP 3

    Oil an A4-sized roasting tin, scrape in the dough and reshape in the tin (see tip, below), gently pushing the dough into the corners. Scatter over the onions, cover with a piece of lightly oiled cling film and leave until puffed up.

  • STEP 4

    Meanwhile, heat oven to 220C/200C fan/gas 7. Using your fingers, lightly dimple the dough all over, drizzle with a little oil and sprinkle with sea salt. Bake for 30 mins until golden brown. Can be made the day before and stored in an airtight container.


The best way to knead and shape the dough by hand is by continually stretching and folding it over on itself, in both directions.
