What happens in a poolish?

What happens in a poolish?

Usually, poolish is fermented at room temperature, and therefore it can’t have high levels of added yeast, or it may over-ferment! Ideal fermentation time for poolish is 15 to 18 hours. Poolish will look a big shaggy ball when just mixed, then it will transform into a very soupy, liquidy, almost batter-like dough.

How do I know when my poolish is ready?

Ripeness is indicated when the surface is covered with small bubbles. If the poolish has risen and then begun to recede (called a “high water mark”) its leavening power is shot.

How long does it take to age in poolish?

You can prepare your poolish up to 8 hours but also up to 16 hours in advance. But you have to adjust the amount of instant dry yeast you use. Logically, the more time a pre-ferment gets, the less yeast you have to use.

What is the consistency of poolish?

Poolish has a loose consistency and is typically made with equal parts water and flour with a small percentage of commercial yeast. Biga, which is more like a dough than a batter, has a lower hydration than poolish and sponge, which is mostly used for enriched doughs, contains milk, eggs, butter, and/or sugar.

Is poolish necessary?

It’s important to make sure your poolish, biga, or levain has properly fermented—if not, your loaf will be blander and denser than intended. Yes, bread that’s made with a preferment is going to take some planning ahead. But the superior results are worth it.

Can I put poolish in the fridge?

If you are not using the starter right away, you can store it in the refrigerator, though I suggest keeping it for no more than 8 hours. Bring to cool room temperature before using.

Why did my poolish collapse?

If the poolish is over-fermented and totally collapses, then it’s probably over-acidic and may cause problems in the final dough. It’s good that you’re taking notes on the evolution of your poolish, as that it is really the only way to establish a predictable timetable for your particular baking setting.

What should my poolish look like?

They should look active and alive—the surface of a ripe poolish should be covered in small bubbles, and if you look closely, you may even see one come to the surface (a baker’s shooting star?).

What is the advantage of a poolish?

The use of a poolish is well suited to domestic flour and lends tolerance to longer fermentation times.

What is the purpose of poolish?

Poolish, also called liquid biga or yeast, is a leavening method used in indirect baking. It is a pre-ferment that makes baked goods soft, fragrant and aromatic, especially bread and pizza. Poolish is made by mixing water, flour and yeast together, in varying proportions.

Should poolish be covered?

Thanks! It does not require any air but it does produce a lot of CO2 that has to go someplace. I keep my starter in a mason jar with the lid loosely closed which will let the gas out. When I make a pre-ferment based pizza (the Johnny’s clone for example), I just cover the bowl with the preferment with plastic wrap.

What should poolish smell like?

It should smell yeasty at first and feel a little hot from the small amount of alcohol fermentation generates. The poolish should also feel a slightly sticky and slimy and taste shockingly sweet, followed by nutty and fruity flavors.
