I keep thinking about having a go, not tried yet.
I regularly make sourdough bread
Once the procedure has been understood, eating sourdough from likes of Waitrose and M&S leaves you wanting.
If you are interested, can send you detail by PM on how to make artisan sourdough.
Sourdough bread is made using culture that is prepared over several days. Airborne natural yeasts etc make this culture active. Direct analogy is culture to make yogurt.
Commercial yeast can be used but proper sourdough is made with aforementioned culture. The bread is made with water, flour and salt- no other additive. Lower glycemic index and healthier for the gut
Bread as we know it is made with commercial yeast that reacts with added sugar to create bubbles that impart the spongy texture to the loaf. The reaction is rapid hence bread can be made quite quickly.
Sourdough on the other hand is a slow process.
Let the culture that takes between 7- 10 days be known as starter. The starter stays with you like a resident in your house. You take an amount out of it and replace that amount back into the jar as 50% water and 50% flour so original amount stays the same. This addition keeps the living culture thriving with fed.
Amount taken out of the jar- this culture is one third amount with water and flour added making up the remainder. This mix takes around 6 hours to be fully active.
On average 70% water is added to it in preparation to making sourdough (percentages are in relation to flour weight)
Dough is made which is stretched ( over 5 to 6 hours) and folded. Different people say different things. You will find your happy medium regardless of what the pundits say.
Salt as of is 2%
I have been making bread for several years and am still learning.
The procedure of making sourdough is simple yet flour source and type can have profound effect on texture, taste snd crumb
