whole wheat flour directly. In this case look out for a strong whole wheat

As explained earlier both the protease enzyme and bacteria break down your

become more extensible. This is because the rubber layers of your care tire
become more extensible. This is because the rubber layers of your car tire
are slowly converted and eaten. Ultimately your car tire turns into a balloon
that can very easily be inflated. When waiting too long the
balloon will burst. You will have no gluten left anymore and your dough
becomes very sticky. Finding the sweet spot of enough rubber eating and not

finishing the fermentation period in 1 hour. If you were to slow down things
the dough would look completely different.
Try this again and use way less yeast. This is the
secret of the Neapolitan Pizza. Only a tiny bit of yeast is used to make the
dough. In fact my default pizza recipe calls for around 150 milligrams of dry
yeast per one kilogram of flour. Give it a shot yourself the next time you

This is also commonly known as the \textit{Bassinage method}. The gluten
bonds have formed at the lower hydration and can then be made more extensible
by adding water and kneading again. This is a great trick to make
