SOURDOUGH and POOLISH - What are the DIFFERENCES?

In this video we are looking at the differences of Sourdough and Poolish. I'll be showing you both a poolish and a sourdough pre-ferment. Depending on the kind of bread you want to bake you should choose either between a poolish or a sourdough. To make the sourdough you take a batch of your mother dough and mix it with the new dough. For the poolish you use commercial yeast and mix it with a bit of flour. You let that ferment for a day or so before mixing it in your final dough. Which dough to choose really depends on what you want to bake. Sometimes you want to have a very strong yeasty smell and flavor, go with the poolish then. If you want to have a distinct sour taste, sourdough is preferred. Sourdough dough also degrades faster than poolish based dough. If you want to ferment for a very long time, poolish might be the better option.
