I’ve tried a few times over the years, and I can keep a hellacious starter, but can’t get the bread right. It has no zing, and sometimes I need to add yeast anyway. 🤷♂️
Here is one post on how I do it. I have since changed it to be 70% whole wheat. Comes out the same every time.
I keep it in the fridge once cut in half. When I eat it it's usually toasted anyway. Lasts a long time.
Around noon take my starter out of the fridge. Let it warm up for an hour on the counter.
Feed the starter - I have weighed all my containers empty and have the weights recorded. Double what is there, ie if I have 50 grams of starter I add 25g flour and 25g water. Let it sit on the counter
A few hours later I start a sponge. I use half my starter, and then make a total of 350g of new starter. Return my starter to the fridge.
Proof the sponge overnight in the cupboard. The next morning it is ready.
Day of baking - starting after coffee
Pour the sponge into my mixing bowl and weigh to see exactly how much I have. I am never under weight, always over
Add and mix in 390g water. The water has been sitting out on the counter in a Brita.
Add 300g Whole Wheat and 300g of White. I am using Organic flour I get from Walmart of all places.
Mix and cover and place in my cupboard. Measure out 12g salt.
30 minutes later add salt and work it in by hand
Two to three stretches spaced out every 30 minutes.
Form into a "ball" and place in my proofing container lined with parchment paper
Let it rise all afternoon. Bake at 400F for 40 minutes in a covered crockpot.
Cool on a rack for the rest of the night (I have been asked to serve hot bread but I refuse)
