What is hydration and how does it affect pizza dough?Updated 7 months ago
Hydration refers to the amount of water in dough. It's expressed as a
percentage relative to the amount of flour. For example, if you have 1000g of
flour and 700g of water, you'll have 70% hydration.
By increasing or decreasing the hydration you can significantly alter the end
result of your pizza. Higher hydration improves flavor and texture but it also
makes handling the dough more difficult. As a general rule of thumb, 60% is a
good starting point when you begin making your own dough.
Here's how hydration affects your dough:
**Stretch: **Higher hydration makes your dough more elastic, which means
it'll be easier to stretch and less prone to tearing.
**Proving time****: **Higher hydration speeds up yeast reaction, which
results in shorter proving times.
**Texture: **Higher hydration leads to a more flexible gluten structure. This
means that larger air bubbles will be trapped inside the dough which will then
expand in the oven to create airier crusts.
**Flavor: **Higher hydration results in a more developed flavor.
**Stickiness: **Higher hydration means your dough will be stickier, which can
make it difficult to handle. Here are some tips that will help:
* Use the [Ooni Pizza Dough Scraper](https://uk.ooni.com/products/ooni-pizza-dough-scraper?_pos=3&_sid=daf66d28e&_ss=r) when removing your dough from the tray.
* Use a small amount of water or oil on your hands when handling the dough. You may be tempted to add more flour but try to avoid doing this as it will lead to a denser crust.
* When stretching out your dough to form a pizza, lightly coat the dough ball with fine semolina.
Higher hydration dough takes practice - we'd suggest starting with 60% and
working up over time. We'd also recommend using the [Ooni
