Questions and Answers

What is the main reason why Professor Calvel used pâte fermentée in his hybrid mix method?

To allow the bacteria to create accentuated amounts of lactic acid (correct)

To improve the gluten development in the dough

To reduce the bulk fermentation time to 1-2 hours

To minimize the effect of enzymes on the dough

What is the primary benefit of the autolyse period in terms of gluten development?

It enables the gluten-forming proteins to bond and organize passively (correct)

It increases the activity of enzymes in the flour

Study Notes

Autolyse and Mixing Methods

Professor Calvel developed the hybrid mix method, also known as the improved mix method, in the 1960s, drawing on his knowledge of mixing and fermentation techniques from the 1920s.
Calvel used pâte fermentée (pre-fermented dough) to create accentuated amounts of lactic acid, allowing for strong dough and good-tasting bread in 1-2 hours of bulk fermentation.

Autolyse Benefits

Autolyse, a defined rest period between ingredient incorporation and gluten development, allows gluten-forming proteins to bond and organize passively, reducing the need for excessive turning and preserving carotene pigments in the flour.
Autolyse enables enzymes to become more active, with protease working to degrade protein bonds and make the dough more extensible.

Autolyse Disadvantages

The autolyse period requires a 15-20 minute wait, which can be inconvenient or inefficient, especially when dealing with multiple bowls of partially mixed dough.
Mixers with nonremovable bowls pose an even bigger dilemma when including the autolyse.

Comparison to Other Methods

Using poolish or liquid levain instead of autolyse can add flavor and extensibility to baguette dough while enabling a shortened mix time and no downtime.
The improved mix method, which includes autolyse, offers a practical alternative to the intensive mix method, with better flavor, volume, and shelf life.

Improved Mix Method

Reducing mix time on second speed to 3-4 minutes (instead of 10-15 minutes) allows for considerable gluten development prior to bulk fermentation.
Adding one set of folds during fermentation and using enough pre-ferment to supply organic acids enables the production of baguettes in 4.5-5 hours.
