To make the sfincione dough, dissolve the yeast in the water and leave for 5 minutes to activate
Once the yeast has started to foam a little, add the flours, then the salt and oil. Knead well, cover with a damp cloth, and let rise for 1 hour at 30°C
Meanwhile, make the passata. Lightly fry the garlic and basil in a dash of oil. Add the tomato pulp and season with the salt and sugar
Stir well, allowing the flavours to infuse and the tomatoes to heat through (about 8 minutes), then remove the basil sprigs and transfer the sauce to a blender. Blitz until very smooth, then set aside
Preheat the oven to 180°C/gas mark 4
Roll out the dough and place in the baking tray. Garnish with the anchovy, Caciocavallo cheese, passata, grated Ragusano cheese, breadcrumbs, oregano and extra virgin olive oil
Bake for 25 minutes, then remove and allow to cool slightly before slicing and serving
