Choose a strictly white flour, with nothing inside.
DO NOT use:
· flour with baking powder already mixed in,
· mixtures of meals,
· other types of flour that lately are sweeping in supermarkets.
Why?
Because with this recipe for pizza margherita seek simplicity.So the flour that you already have in the pantry will be fine: a normal white flour that is usually defined in Italian flour "0." Give preference to local flour mills.
It is optional
