So what's a poolish?
It's a pre-ferment. Equal parts flour and water, a tiny pinch of yeast, mixed into a loose batter and left overnight. By morning it's doubled, full of bubbles and smells a bit like b**r. That's the yeast getting a head start before the real dough is even made.
Why bother?
Mostly for the flavour. A long, slow ferment builds a depth you can't get from a dough made and baked the same day. Slightly sweet, a little nutty, with a gentle tang.
Texture too. Poolish makes the dough stretchier and easier to open by hand, and you get a lighter, crispier base with a properly airy crust.
And it's consistent. I love sourdough, but a starter has moods. When you're cooking for a crowd, you want a dough that behaves the same way every time.
Tomorrow this gets mixed into the main dough, balled up and sent to the fridge for a long cold ferment. Pizza starts days before you eat it.
