Prep Time: 20 minutes
Cook Time: 30 minutes
Ready In: 2 hours
1tsp dried active yeast
1tbsp caster sugar
450g (14 1⁄2oz) plain flour
1tsp fennel seeds, crushed, plus extra to garnish
1tsp chopped rosemary, plus extra sprigs to garnish
2 tbsp olive oil
250g (8oz) black grapes
semolina, for dusting (optional)
1. Add the yeast and sugar to 350ml (12fl oz) warm water. Stir and set aside.
2. In a large bowl, combine the flour, fennel seeds, chopped rosemary and 1tsp salt. Add the yeast liquid, mixing with a wooden spoon until it forms a dough (if it sticks to the bowl, add a little more flour). Using your hands, knead for 10 minutes until smooth.
3. Pour 1 tbsp of the oil into a bowl. Roll the dough in the oil and shape into a ball. Cover with clingfilm and leave in a warm, draft-free place for 1–2 hours until the dough has doubled in size.
4. Remove the clingfilm and knead half the grapes through the dough, knocking out some of the air as you go.
5. Scatter a large baking tray with the semolina, polenta or flour (this helps it glide off the tray more easily), using your hands or a rolling pin, stretch out the dough, until roughly the size of the tray. Cover with a tea towel and leave to rise for a further 30 minutes.
6. Meanwhile, preheat the oven to its highest temperature and put a lined baking sheet in to heat up.
7. Press the remaining grapes and some rosemary sprigs into the surface of the dough, then drizzle with the remaining oil and scatter with sea salt and the extra fennel seeds. Slide the dough onto the preheated tray and bake for 25–30 minutes until golden. Serve warm.
