Since gluten isn’t an issue for you, why not try it. Here is one of the best sites for sour dough information. https://breadtopia.com/sourdough-starter-videos/
I suggest you use the ancient grains, like spelt or my favorite stone ground organic Einkorn flour The wheat flours at your local grocery has been altered so much it basically has no nutrition in it. This flour bothered me less than any other of the alternative wheat strains. It made wonderfully rich flavored sour dough starter. You can get it at Breadtopia website and some other sources. I trusted Breadtopia, so I always ordered from them.
I still have some dried starter tucked away in case I ever lose my mind and try to do the breads I love so much again. I think my healthy body is gonna win out, but JIK, I have some saved.
There are few pleasures richer than a hot loaf of sour dough you crafted yourself. Good luck with it.
Once you try using just the wheat flour, you might want to mix in some nut flour to see if you can cut back the carbs a bit. As long as you have a slightly higher carb allowance and gluten doesn’t bother you, a slice here and there should be ok. But I sure couldn’t stop at one slice, I am a breadaddict working on year 4 of
sobriety.
Happy Baking.
