Master the Sourdough Croissant

Learn the exact process behind the pastry that helped take Proof from a garage to five bakeries.

Most people associate sourdough with bread, but at Proof, our laminated pastries have been the lifeblood of the business since day one. Without them, our sales may never have been strong enough to sustain and grow the entire operation.

In this course, you will learn our complete process from start to finish:

  • Mixing the dough

  • Lamination and shaping

  • Fermentation and proofing

  • Baking for proper lift and structure

You will also learn how to turn sourdough croissants into a profitable bakery product, including labor, timing, margins and production.

This is the exact process we use at Proof, where one dough now represents half of our business.
