Calvel's Autolysis
I haven't posted here in years, but now I come full circle and return
to ask for assistance once again. I just obtained a copy of the english translation by Wirtz and MacGuire of Le Gout du Pain by Raymond Calvel. I think I've sorted through many of the details; I have a starter raring to go, and this coming weekend I should be ready to make my apartment smell good, but I need some help first. I think I may be over thinking this, but in the book, autolysis is mentioned many times as being one of the magic discoveries to making bread taste good, although Calvel never actually says what it is except in the recipes, and that still leaves me wishing more information was given. In the recipe for Pain au Levain (Exhibit 10-1), there are 2 sponge steps and the final dough stage includes autolysis for 30 minutes. The footnote in this recipe for autolysis says: "Dough autolysis refers to a rest period that occurs after 5 min of mixing a fraction of the flour and part of the water excluding the remaining ingredients." I guess I am most baffled that there are no amounts (or even hydration percentages) for autolysis given. Could someone point me in the right direction?? What is autolysis, and how do you do it?? What hydration level do you autolyse at? What percentage of the final dough?? At what temperature?? By the way... I am really enjoying calvel's work. I can't wait to see what it does to my bread. Thanks, -Matt |

I do not remember ever seeing anything about the specific proportions and so have tried it with everything in the dough (again, except the salt.) I will add that I have not seen any great benefit, but hey, I'm not Calvel. All the best, -- Kenneth If you email... Please remove the "SPAMLESS." |

There is a decent, plain language definition: http://www.heartlandmill.com/baker_pages/basics.htm "Autolyse (or dough autolysis) A process in which the flour and water in a formula are mixed together at low speed and allowed to sit for a rest period, usually of 20 minutes. This pre-hydration allows for better links between gluten and starches and results in shorter mix times and improved dough extensibility. Loaves made with autolysed dough will be easier to shape and will have more volume and better crumb structure. Due to the shorter mix time (less oxidation), the dough may retain more of the carotenoid pigment responsible for the creamy-yellow color desired in well-crafted bread." Some recipes will be specific in the amounts of flour and water included in the autolyze, and hold some back. Some include all the flour and water. The pre-ferment is added later, usually. Can it vary? You bet. Depends on who has written the recipe, If you are using a recipe that does not include an autolyse, you can easily add one in by combining your flour and water up front, giving it a bit of a mix, then letting the whole thing sit for 20-30 minutes. There is nothing hard and fast about its use insofar as hydration levels for a home baker. Use the proportions your recipe calls for. You are not forbidden to add more flour or water later on, either. Boron |

I follow Kenneth's direction. While I too have not seen any marked difference in the final product, my mixer (Kenwood Chef) has been most grateful.

Calvel's Autolysis
as someone who actually has Calvel's book I can say Calvel was
promoting autolysis in very specific response to changes in French baking practices that came in in the early 1960's in particular that most French bakers were persuaded they needed to make bread as white and fluffy and as fast as possible. To this end they were sold new high two speed mixers and adding of fava bean flour both of which gave a bread that was highly oxgenised/white and light (almost whipped rather than kneaded) at the expense of flavour. Calvel wanted fava bean flour out and mechanical kneading reduced to a minimum and certainly the 20 minutes rest between initial mixing and main kneading that he uses 'autolysis' to mean is the most significant way to reduce actual total mechanical mixing, by hand or by machine. In my reckoning this 20 minutes cuts total kneading by about a third. I can't really imagine why anybody kneading by hand would want to do this extra work but on the other hand there is no real comparison between the damage to dough structure that a high speed continuous mix can do (leading to complete breakdown of dough structure, over- mixing) and any thing that can be done by hand. In my opinion the most obvious likely effect is that gluten gets a chance to unfurl gently in an autolysis period whereas in continuous mixing its brutally unravelled and probably snapped in some cases. When mixing with my Arotofex mixer I do find that if the last 3% or so of water is added to a dough after an autolysis period an hydration can be achieved that is higher (less likely to over mix, dough easier to handle afterwards.more self cohesive) than if all water is added at beginning. I don't think it is necessarily true that Calvel's use of the word is so inappropriate if you believe the biological sense to be the correct one (see http://en.wikipedia.org/wiki/Autolysis) since it is certainly true that amalyse enzymes http://en.wikipedia.org/wiki/Amylase either naturally occurring in wheat flour or included by an addition of rye flour (in which they are much more significantly present - in most years) or by including diastatic malt extract may start their work of breaking down starch into sugars, and complicated sugars into simpler sugars in this 20 minutes. I would therefore suggest that in this respect the nature of a dough after autolysis may be quite different and therefore performs differently when kneaded than dough without this rest. Interestingly another of Calvel's shibboleths was that he advocated adding salt at beginning of mix whereas the prevalent artisanal bakers practice of today seems to be to add at beginning of or during final mix after autolysis. yours Andy Forbes |
