At the end of this course you will be able to:
Refresh a starter with equal weights of starter, warm water and flour until it is active enough to bake with.
Work out your water temperature from the base temperature so each dough lands at the same heat.
Use autolyse and bassinage to build gluten and open the crumb of a baguette.
Check the pH of a liquid sourdough before you use it or move it to the fridge at 4°C.
About this class
This online sourdough course starts with the starter. Lesson #1 refreshes a liquid starter with flour and water at 30 to 35°C, in equal weights, until its pH sits between 4.2 and 4.5, and lesson #2 adds a poolish for comparison.
The breads use the starter in different forms: a baguette with a little fresh yeast, a seeded pavé, a 100% sourdough T80 bread and a couronne bordelaise shaped into a crown. The last three lessons take the same sourdough into a classic croissant, a bicolour croissant and a pineapple pastry.

“We recognize a good baguette not because the exterior is beautiful, but because inside it must be creamy and very nice.”

Key concepts
Sourdough
Bread leavened by naturally occurring lactobacilli and yeast. Taught in lesson #1. (Wikipedia)
Pre-ferment
A fermentation starter made ahead of the final dough, such as poolish or biga. Taught in lesson #2. (Wikipedia)
Baguette
A long, thin French bread with a crisp crust. Taught in lesson #3. (Wikipedia)
Flour types
French flours are graded by ash content, so T80 is darker and less refined than T65. Taught in lesson #5. (Wikipedia)
