Bread Making of Chief Crumb and A Little Bird Crust
By now, the dough must be in much better condition.
Now, Chef Crumb adds leaven and mixes it well, then salt, and starts kneading the dough.
Salt should be added after mixing leaven (or yeast) and other ingredients. Because salt has the ability to kill germs; it hinders the fermentation of yeast. There needs to be a sort of middle ground in between salt and yeast to prevent this.
However, salt can control the fermentation of dough and improve the taste of bread. It can also control and tighten the gluten structure, so that the texture of the crumb and the color of the crust will improve.
If you are making bread with the straight dough method, without Autlyse, salt can be mixed with flour at first, and the yeast with water.
