Stromboli recipe
 This is a really fantastic recipe for a kind of filled bread, a bit like a rolled-up pizza! It can also be made with ready-made pizza or bread dough and bought tomato pizza sauce. We cooked this at Si’s sister’s family feast at her house near Florence. 450g/1lb strong white flour, plus extra for dusting50g/1oz semolina1 x 7g/¾oz sachet of fast-action dried yeast2 tsp flaked sea salt2 tbsp olive oil, plus extra for greasing325ml/11fl oz warm water 450g/1lb strong white flour, plus extra for dusting 50g/1oz semolina 1 x 7g/¾oz sachet of fast-action dried yeast 2 tsp flaked sea salt 2 tbsp olive oil, plus extra for greasing 325ml/11fl oz warm water 2 tbsp olive oil1 small onion, finely chopped2 cloves garlic, crushed400g/14oz can chopped tomatoes½ tsp dried oregano1 tsp caster sugar8 slices of prosciutto125g/4½oz mozzarellalarge handful fresh basil leavesflaked sea saltfreshly ground black pepper 2 tbsp olive oil 1 small onion, finely chopped 2 cloves garlic, crushed 400g/14oz can chopped tomatoes ½ tsp dried oregano 1 tsp caster sugar 8 slices of prosciutto 125g/4½oz mozzarella large handful fresh basil leaves flaked sea salt freshly ground black pepper good olive oil and balsamic vinegar good olive oil and balsamic vinegar Method To make the dough, sift the flour into a large bowl and stir in the semolina and yeast. Mix the sea salt and olive oil with the water and stir into the flour. Mix with a large wooden spoon until the dough comes together and forms a soft, spongy ball.Transfer the dough to a lightly floured surface and knead it for five minutes until smooth. Place the dough into a bowl, cover with lightly oiled cling film and leave it for about an hour in a warm place or until it has doubled in size.While the dough is rising, make the tomato sauce. Heat one tablespoon of the olive oil in a nonstick frying pan and fry the onion over a low heat for five minutes until softened and lightly browned. Stir regularly and add the garlic for the last minute of the cooking time. Tip the tomatoes into the pan and add the oregano and caster sugar. Season with salt and pepper. Place over a fairly high heat and cook the sauce for 5–8 minutes until very thick, stirring constantly. Remove the pan from the heat and leave the sauce to cool.Roll out the dough on a lightly floured surface into a rectangle measuring about 44cm x 32cm/17in x 13in.Spread the tomato mixture over the dough, leaving a 2cm border around the edge. Lay the prosciutto in a single layer over the sauce. Tear the mozzarella into small pieces and dot over the prosciutto, then scatter the basil leaves on top.Tuck in the two short ends and roll the stromboli up firmly to enclose the filling. Place it, seal-side down, on a large baking sheet lined with baking parchment and leave to rise for 30 minutes.Preheat the oven to 200C/400F/Gas 6. Brush the remaining oil over the dough, season with a little more salt and pepper and bake the stromboli for 25–30 minutes until well risen and golden brown.
