In a large enough bowl, mix together with a fork flour, sultanas, sugar and the olive oil. Then add some warm water, until you obtain a thick batter.
Take an oven dish and oil it slightly. Pour the batter in it then sprinkle it with the pinenuts and, if you want, with some rosemary leaves. Bake in the oven at 200 degrees celsius (390 Fahrenheit) for about an hour. Let it cool, slice it and serve it with a nice cup of coffee and a dollop of whipped cream.
