Two dough formula, this recipe will test the ability of your LM starter! 

Abandoned 3 times, this 4th attempt I saw through to the end...

I had to tweak the process timing to match my schedule and gave the final laminated dough a fridge proof for 36 hours.

I had originally planned to make this into Pan Aux Raisin but I didn't get around to making the creme pat and rum soaking the raisins. Next time!

Congratulations!!! Great Croissants! Lovely crumb! I'm getting hungry:D

The leavened puff pastry from TTC's book has been a very long time on my TODO list. I tried 3 times in the past 2 years. My biggest issue ist laminating the butter.

Thanks sparkfan. 

I found this really easy to laminate, almost too easy, meaning I could do several folds in one go. As always fermentation and the effects of the LM have a significant impact on the final dough properties. The issue that can arise in panettone where butter is difficult incorporate during mixing presents itself as an overly resistant dough that resists extension during laminating croissant dough. In both cases the root cause is the same, the gluten network becomes inextensible. This is attributed to a LM stater that is "too lactic"

Tip: If you think your LM might be too lactic or lead to a dough that suffers with resistant gluten, I have discovered that if you give the LM a bagnetto before use this could help significantly.

BTW, did you consider the folding butter in the  Su, Cu and Hu calculations for the final dough? In the book are the same number, but imo  the folding butter shouldn't be counted in the final numbers. The folding butter has no impact on the fermentation.

That's a fair point since the fold in butter is not part of the fermenting dough. My spreadsheet auto calculates Su, Hu and Cu. I would need to move butter down into the add-ins box (the last three lines on the 2nd dough panel) to prevent it from contributing to those figures, which I can do... Although, I tend to think these stats, namely sugar concentration, are more valuable for the first dough, so I didn't care too much about the notation in the second dough.

Made me chuckle🤣

Su, Hu and Cu are notations of the Universal Method as devised by Thomas Teffri-Chambelland. It's a system relevant to enriched doughs which attempts to quantify water, sugar and concentration of sugar.

Each ingredient by weight is prescribed a percentage of solids that it contains and anything that isn't solids is water. From this, the total amount of water contained within the dough can be calculated.


Per dough mass:

Su = sugar and sugar containing ingredients (%)

Hu = water (total solids deducted from the dough mass) (%)

Cu = Su/Hu

 

According to Thomas, Cu values greater than 50 can arrest fermentation completely.

That is a lot of science and math. I wonder how the old time chef pâtissier, reconciled and quantified  these variables? Smile...

All jokes aside, There is no way to argue with your consistent stellar results. While baking can be a vocation, learned through trial and error; in so many ways it is a science!

Looks good, Michael!

This gives me the courage to test my bran starter on true sourdough croissants

(and such a coincidence I have croissant dough fermenting!)

I just baked a batch of true SD croissants, still based on my previous formula. I did sugarred 50% hydration 3 stages levain.

Eventhough they took 18 hours to proof and no oven spring, they taste reeaaaally pleasant, really really good. Prolly the best-flavored plain croissant I've ever shove down my throat. The fermentation flavor managed to keep up with the enrichment flavor. The acidity was surprisingly mild despite the proofing time, and complement the fat really well

I feel single stage levain gives better rise, and three stages levain gives better flavor. Since I feel the flavor was pleasant, I might try single stage next time to see whether it gives better rise, putting all the salt,  powdered milk and butter in it to make it more hostile environment

I'll let you know when I get presentable cosmetic results

What a beautiful outcome and gorgeous crumb. Well done!

Didn't realise how much egg went into croissants.

Thanks Jon.

Regarding eggs, the traditional yeasted recipe doesn't actually use any egg at all, just milk and sugar. It tends to be that Italian recipes and particularly LM recipes use eggs as they help balance the acidity from the natural leaven.

Lievito madre (LM) is the Italian name for a sourdough starter culture like levain in French and leaven in English. The term is broader in definition than pasta madre (PM). But most will use these terms to refer to a panettone type starter, meaning it is stiff (approx. 45-50% hydration) and made with refined white flour.

Lievito madre = mother leaven / yeast [The Italian word for yeast is leaven (lievito)]

Pasta madre = mother dough

In Italian texts, LM could refer to a liquid sourdough whereas pasta madre is defining a dough consistency.

Getting them jiggly before going into bake is definitely key! Indeed, I am pretty happy overall. Still, a few things to improve upon...


Michael

You achieved consistent shaping and sizing, as well as beautiful coloring from the bake.  Good execution all around.

Paul

Great baking!  Very interesting with the eggs.  I’m sure it adds another layer of richness to these dietetic 😉 beauties☺️

They're even better with nutella 😁 I've got breakfast sorted for the week!


Michael

Impressive loft and just lovely.

FYI, the French bakery recipe I’ve been using for the last several years includes eggs (though only at 5%) as well as butter (also at 5%) milk (25%), water (25%) and sugar (15%).
