Step by step

Take a large bowl and transfer the flour to it

Tips
If you want to, you can also use starter yeast in dough rather than baking powder. The outcome will be the same. Bear in mind that for half a kilo of flour you will need 12g of traditional yeast.
Trivia
Did you know that salt inhibits the action of baking powder? So don’t dissolve salt and baking powder together in the same water, or the rise won’t work properly!
