Starter timing. If you mix flour and water only, then rest, that’s an autolyse. If you throw the starter in with it, that’s a fermentolyse. Different thing, different name. The reason it matters is acid. A true autolyse sits at neutral pH, and that lets the enzymes in the flour work without interference.
Protease loosens the protein, amylase starts breaking starch into sugar. You get extensibility. The dough stretches instead of fighting you.
Add the starter up front and fermentation begins on minute one. The acid starts tightening things sooner, bulk runs shorter, and you’ve saved yourself a step.
So who’s right? Both. If you’re running weak flour, a lot of whole grain, or 80 percent hydration and you need that dough to stretch, autolyse first. If you’re using strong bread flour at 70 percent and you want fewer steps, mix it all together like I do and move on with your day.
Coil fold versus slap and fold. These aren’t competing. They’re doing two different jobs at two different times.
Slap and fold builds gluten. It’s mechanical, it’s aggressive, and it’s what you reach for early when the dough is slack and there’s no structure yet. Front-load the work, get strength fast.
Coil fold maintains. It’s for during bulk, after fermentation is producing gas. It organizes the gluten and adds a little tension without knocking the air out of what you just spent four hours building.
Slap early. Coil later. Somebody doing nothing but coil folds is letting time and hydration do the developing, and that works fine if the schedule allows.
Nobody explains this because the honest answer is “depends on your flour, your hydration, and your clock.” Doesn’t fit on a thumbnail. But it’s the truth.
Perfection is not required. Progress is.
