Hi, I give you my personal version, which is very easy and particularly soft!
1/2 kg white flour OO, 25 gr baking powder, milk, olive oil, salt
First of all melt the baking powder or the fresh ywalt with a bit of warm water, and when it's completely melt, drop the flour and mix with your hands.
Add 1 glass of milk, or more, it depends on how you 'work with hands' the mixture!
Then add the olive oil: take a glass and measure 2 fingers (it's about 3 cm from the bottom). Work the mixture with your hands and at the end when you realise the mixture is soft and not too dry, add a pinch of salt. Let it double its size in a warm place, placing it into a bowl, covered with some plastic.
It's important that the mixture is soft and not too dry, otherwise it won't double its size.
Let me know ;-)
