Sourdough Panettone and Viennoiserie by Thomas Teffri-Chambelland

Sourdough Panettone and Viennoiserie by Thomas Teffri-Chambelland is a technical study of naturally leavened sweet dough, connecting the microbiology of sourdough with the practical realities of producing panettone, croissants, brioche, kouglof and other enriched pastries.

Teffri-Chambelland approaches the subject from an unusual perspective: he trained as a biologist before becoming a baker. The opening theory section therefore goes considerably deeper than a typical recipe book, examining the microorganisms involved in fermentation, changes in bacterial populations, the role of minority bacteria, dextrin production and the biological processes that influence enriched sourdough.

The purpose of that science is practical control. Rather than teaching one panettone formula as a fixed solution, the book develops a broader method for understanding how naturally leavened pastry works. That framework can then be used to analyse existing formulas, troubleshoot fermentation and eventually design new sweet sourdough products.

The practical section translates the theory into production: maintaining and preparing the starter, choosing ingredients and equipment, mixing, fermentation, shaping and preparing inclusions such as candied fruit. Detailed step-by-step sequences connect biological principles with what a baker actually sees and handles at the bench.

The final section contains more than 20 detailed formulas spanning panettone, croissant, brioche and kouglof, with additional contributions from bakers including Ezio Marinato, Mauro Morandin, Alfonso Pepe, Daniel Jordà, Miquel Saborit, Christophe Louie, Emmanuel Revuz and Roy Shvartzapel.

For professional bakers, instructors and advanced enthusiasts, Sourdough Panettone and Viennoiserie is particularly valuable because it does not separate fermentation science from production. It provides the knowledge needed not simply to follow a naturally leavened pastry formula, but to understand why it behaves the way it does.
