In the evening, make a sourdough from the first three ingredients and cover and leave to stand overnight at room temperature.
The next morning add the remaining ingredients and knead in the food processor for 5 minutes. Immediately divide the dough into 3 small loaf pan (20x10cm) (about 700 g dough per pan) and cover and let rise for about 90 minutes. Brush with a little oil and dip.
