He has published numerous research papers on the topic and is often sought after for his expertise. Mason is also an avid home baker and enjoys experimenting with unique sourdough recipes.
Regular Pizza Dough:
Regular pizza dough is made using commercial yeast, which is a single-celled microorganism that ferments the dough and produces carbon dioxide gas. This gas gets trapped in the dough, causing it to rise and create a light and airy texture. Commercial yeast is readily available and provides a quick and consistent rise, making it a popular choice for many pizza recipes.
Sourdough Pizza Crust:
On the other hand, sourdough pizza crust is made using a sourdough starter, which is a fermented mixture of flour and water. The starter contains wild yeast and lactic acid bacteria, which work together to ferment the dough. The wild yeast in the starter feeds on the sugars in the dough and produces carbon dioxide gas, just like commercial yeast. However, the fermentation process in sourdough is slower and more complex, resulting in a unique flavor profile and texture.
The Role of Yeast in Sourdough Pizza Crust:
While sourdough starter contains wild yeast, it may not always provide enough leavening power on its own to create a light and airy pizza crust. This is especially true for sourdough pizza crust, which tends to be thicker and chewier than regular pizza dough. To achieve the desired rise and texture, some recipes call for the addition of a small amount of commercial yeast along with the sourdough starter.
Benefits of Using Yeast in Sourdough Pizza Crust:
Using a combination of sourdough starter and commercial yeast in sourdough pizza crust offers several benefits. Firstly, it provides a more reliable and consistent rise, ensuring that the crust is light and fluffy. Secondly, it speeds up the fermentation process, allowing you to enjoy your homemade pizza sooner. Lastly, it helps to balance the flavors in the dough, as the wild yeast in the sourdough starter can sometimes produce a tangy or sour taste that may not be desired in a pizza crust.
Conclusion:
In summary, yeast is required for sourdough pizza crust to ensure a consistent rise, a desirable texture, and a balanced flavor profile. While sourdough starter contains wild yeast, it may not always provide enough leavening power on its own. By using a combination of sourdough starter and commercial yeast, you can achieve the best of both worlds - the unique flavors and fermentation of sourdough, along with the reliable rise and texture of regular pizza dough. So go ahead and experiment with different recipes to find the perfect balance for your sourdough pizza crust!
