Keto Sourdough Starter

I have had a helluva time trying to make a stable sour starter with my Baking mix. Even with faithful feedings I find it starts to smell awful and simply doesn't have enough oomph to raise a loaf on its own. So I got sneaky. I began with a healthy all purpose flour starter. Instead of feeding it AP flour and water, I fed it Ketonia Baking Mix and water. Since after the first feeding I discard half the starter with each feeding, it takes only about a week before the starter becomes a full keto starter! It still needs a bit of yeast to get a good rise for bread, but it's delicious as a sourdough cracker! You will need to get hold of 4 ounces of fresh, bubbly sourdough starter. After 2 years of quarantine, it shouldn't be too hard. If all else fails, King Arthur Flour sells a starter mix! Here is the feeding schedule. Cracker recipe will follow!

Method

In a scrupulously clean glass jar, weigh out 4 oz. starter and 2 oz. Ketonia mix. Mix thoroughly. Cover. leave on counter overnight.
At roughly the same time of day, discard 5 oz (roughly half) of the starter. Add 1 oz mix and 2 oz water. Mix thoroughly and cover. Let sit on counter overnight.
Again, at roughly the same time of day discard half the starter. This will be about 4 oz now. You should be getting some bubbles in the starter. let sit on counter overnight.
Repeat, discarding half (4 oz. or so) and feeding 1 oz mix and 2 oz water.
Repeat, discarding half (4 oz. or so) and feeding 1 oz mix and 2 oz water.
Repeat, discarding half (4 oz. or so) and feeding 1 oz mix and 2 oz water. you should have an active starter by now. It should smell sweet, not boozy or, god forbid, unpleasant. If it does, unfortunately, you’ll have to start over.
You can use the starter now. You should have about 8 oz.
