If you think you can replace water with another liquid in making sourdough bread, think twice.
I do yoghurt at home and sometimes it makes whey. As this is such a great ingredient with high protein content, I wanted to use it for bread.
The acidic environment of whey and its foreign protein affected the dough of this bread and some extra effort was needed to rescue this dough.
This is an interesting experience to bake bread. More than following a recipe, it is very important to read the dough. When I noticed that things were not OK, I had to adjust my steps and my techniques to correct the dough.
The adventure in making this bread is recorded here:
What I like the most with bread experiences is that you get a lot of lessons learned out of them. For example, this is what I learned by making this bread:
1. Sour whey does affect the dough by weakening the gluten development.
2. More sour whey in bread liquid requires extra handling and may lead to inconsistent baking.
3. You may keep higher whey quantities but use sweet whey, that is less acidic.
4. For an easier bread, reduce the hydration in this recipe by lowering the whey quantity (with 50g, let's say).
Although tricky, I am happy with these loaves: crunchy crust, soft crumb and what a flavour ...
