After adding the comments to Sneaky Tricksey Food Manufacturers, I am having another go at sourdough bread.
I am no longer gluten intolerant, and I tried my hand at sourdough for a brief period. Then my husband was diagnosed with diabetes, and as a result nearly all carbs are banned from our house. Goodbye sourdough starter! But after many years of searching, he has found a low-carb bread that he likes, and I am restarting my sourdough starter for myself. I have bread very infrequently, but once in a while you just have to have a grilled cheese sandwich with tomato soup LOL.
These are the instructions I follow – very simple and clear.
If you can’t mill your own grain please give King Arthur a try. I trust their flour more than other brands (no, they are not paying me to say this).
I have thought about what to do at the spring feasts. On the fourteenth day of the first month, I will be discarding my starter and setting out fresh flour and water from scratch to work for the week of Unleavened Bread. It might be ready to use when the holiday ends – that is likely how the Torah observant did it for millennia.
