Yudane pumpernickel sourdough baguette
I decided to try a pumpernickel yudane sourdough baguette.
- pumpernickel means freshly-milled whole grain rye kernels
- yudane means a process of gelatinizing a portion of flour and mixing it into the dough. The portion is 20% of total flour weight with an equal weight of boiling water mixed in, then left to sit overnight. Gelatinizing the dough helps soften all the bran in fresh milled kernels, and gives a moist, creamy texture and soft chew
- baguette means my low-fi version of Maurizio Leo’s sourdough baguette, made in half lengths
My yudane is 100% freshly ground whole rye kernels. The rest of the dough is Canadian All-Purpose flour.
This is the third in my series of yudane experiments. I previously used toasted buckwheat, and before that, milled wheat. See the links below.
Making the Yudane
I sourced rye kernels from Yu Pik, a packaged brand sold in 1 kilo portions on Amazon, where I have free shipping. I ground the kernels in my Porlex manual coffee grinder on its finest setting. I added boiling filtered water, folded it in, covered in plastic and left on the counter overnight. I then put it in the fridge for an additional 24 hours to see what effect an extended time might have. I have nothing to report there… would have to try a short and long and then compare.
My dough consisted of three main parts: a 30 minute autolyse of all purpose flour, a 100% hydration dark rye flour levain, and the freshly-milled rye yudane. NOTE: I reduced water by 100ml with no noticeable effect on the crumb… but the dough was less slack and easier to work with.
You can see here what it looked like after several 5 minute mixing sessions with 15 minute breaks:
Shape and Bake
Next morning, you can see how much the dough grew during retarded fermentation in the fridge.
I portioned, shaped and proofed the baguettes. Then I slashed them and spritzed with water before putting into a 500F preheated oven with a baking tray already in. I baked 25 mins at 475F.
Loaves, Crumb, Texture, Taste
Here you can see the finished loaves. They look lighter than I expected.
Crisp crust, soft chew inside, buttery texture. Slight tang. Flavour will probably evolve by tomorrow and with toasting. I will update.
I’ve noticed that the two fresh-milled flour yudane versions of my baguette have a more creamy texture than the buckwheat flour version.
