50% Whole Wheat Sourdough Pan Loaf with Poppyseed Crust

Profile picture for user Benito

Still testing high percentage prefermented flour to obtain an open crumb.  So this time stepped up the wholegrain to 50% of the total flour.  The levain still contained 40% of the total flour at the same 1:1 ratio of whole wheat to bread flour as the final dough.  I’m quite happy with how this turned out, but I think I could increase the hydration another 2% to see if that would open up the crumb even more.  I’m really enjoying the poppyseed crusts and once again I added the seeds to the pan after buttering it.

Once the dough was developed, the total time of bulk at 82°F was just under two hours.  Final proofing also at 82°F took only an hour and 50 minutes.

 

For 1 loaf in a 9x4x4” Pullman Pan

Overnight levain build, at 74°F about 10 hours to rise 3x.

In the morning add salt to water and dissolve.  Add levain and mix.

Add flours and knead until good gluten development, I will use my Ankarsrum Assistent and mix until a good windowpane is achieved about 12 mins.

Remove dough from the bowl and do some slap and folds.  Next set up aliquot jar.

Bulk fermentation at 82ºF.

End bulk when aliquot jar reaches 40% rise.

Shape the dough into a batard and place in buttered Pullman pan.  Optional, sprinkle poppyseeds on the bottom and sides of the pullman pan.

Shape and allow an initial final proof warm until 100% rise in aliquot jar, start oven preheat 425ºF preparing for steam bake.

Allow the dough to rise until within 1 cm of the rim of the pan and then bake immediately or about 130% rise in the aliquot jar.

Once oven reaches 425ºF score top of dough and then brush with water.  Optional sprinkle with seeds and then score.  Transfer to oven and bake with steam for 25 mins.  Vent the oven (remove steaming gear) rotate the pan and drop temperature to 350ºF.  Bake for another 30 mins rotating as needed until browned.  Remove from the pan and place directly on the rack baking for another 5-10 mins to firm up the crust if desired.

Overall happy with this bake, the crumb looks great to my eyes and the enhanced wheat flavours from 50% whole wheat are just great.  The convenience of the process going so quickly is also great especially when there is nothing lost in flavour or texture.  

Hope you give a high percentage pff a try in some of your bakes, I’d love to know the results.

Wonderful loaf, Benny. It looks nice and light, great for sandwiches. Well done. Thanks for the formula as I'll give this one a go. I'll adjust up the dough weight as my Pullman is the larger one. 

Cheers, 

Gavin.

Beautiful bake Benny!

Nice ear, nice open crumb, and I love the seeded crust, they're a bit messy but they add a nice crunch. I'll bet it tasted great.

Stellar bake Benny, the recipe that can't be improved is still getting better and better. I too want to give this one a try. 

I did have the thought that putting all/most of the whole grain into the preferment might be something to try just to see if such a fabulous outcome could still be achieved like that. 

For two reasons: putative softening of bran, but also nutritional reasons - phytic acid is reduced by long fermentation. Are these factors that you think about? 

The science behind PA is mostly coming from in vitro studies though, and you managed a very fine crumb so clearly bran isn't a problem here, so perhaps the benefit of doing this isn't so clear either.

Jon, thank you for your comments.  I had thought about making the levain all whole wheat.  I changed my mind at the last minute thinking that it could cause the bread to be more acidic tasting with the bran acting as a buffer and allowing the LAB to produce more acids during fermentation.

I hadn’t given phytic acid a thought in a long time, but what little I know about it, it seems that LAB produce phytases that help reduce the binding capacity of phytic acid.  Also, lower pH also helps speed up the action of phytases. Phytic acid acts as a chelator of minerals so reducing the binding capacity  should make the  minerals more bioavailable and absorbable into our bodies in the GI tract.  What I don’t know is how much time is a factor.  If the dough is acidic enough and the LAB population is large enough, does the dough need to ferment for a long time for the phytases work, or is a few hours enough?  You pose a great question and it isn’t something I was considering I have to admit.  

I believe that phytic acid concentration is greater in the bran and germ portions of grain.  It would make most sense, if you’re wanting to make the minerals more bioavailable, in this formula to make the levain fully whole wheat to give the phytases more time to reduce the phytic acid.

Definitely something to think about.  I’m not sure that I have it all correct.

During WW II, Ireland experienced severe food shortages. the Irish government progressively required that flour for bread be made from higher and higher extraction flour until it went to 100% extraction.  After that, it was found that the incidence of rickets, calcium deficiency, and TB increased in children, even with fortified flours.  Apparently extraction in the range of roughly 90 - 92% did not result in these problems.

Since I read this paper I prefer to sieve out whole grain flour to around 90% extraction (or less, depending on how the screen and flour play together). Of course, if you get enough of these ingredients elsewhere then 100% extraction will be less of a nutritional problem.
