Heat the oven as high as it will go. Make the dough, mix the flour and baking powder with 1tsp of salt. Make a well in the centre and add the water, yogurt and oil and mix together and knead until you have a smooth dough.
Divide the dough into 4 and roll each out to the size of your skillet. Put in one of the pizza bases and cook for a minute until it bubbles lightly, then spread with a ¼ of the sauce and scatter with salami, fennel and cheese.
Put in the oven for 5-6 minutes until golden and melted. As soon as it comes out, drizzle with honey, chilli flakes and scatter over basil leaves. Slide onto a board and repeat with the rest of the pizzas.
