How to cook
Make a starter culture from the yeast dissolved in the milk, salt and a little flour. Leave it to bubble.
Pour it into the flour, add the yoghurt with the baking soda beaten in it. Knead a smooth dough.
If not using it right away, put it in a plastic bag in the fridge. I divided it into 2 parts - I put 1 in the fridge for fritters and used the other 1 for pizzas.
