MutantSpace's Honey Oats Sourdough Variation

I saw MutantSpace's loaf from a question he/she asked and loved the look of the crumb. I do plan to make it as posted but I needed a few loaves this weekend and thought I would just adapt it to sourdough. I think I may have messed up in the salt though and not put enough in. I will know when we taste it.

This recipe made 4 quite small loaves although you could divide it 3 for larger loaves. I wasn't sure that the larger loaves would fit in my Dutch ovens and I wasn't making any for sale so the smaller loaves were just fine. 

1. Toast 75 g each of Sesame seeds and sunflower seeds. 

2. Soak toasted seeds with 225 g rolled oats, 90 g honey, 75 g butter in 360 g hot water. Let sit still almost cool. 

3. Autolyse (not a true autolyse but oh well...) all above with 550 g water, 75 g freshly ground flax, 550 g unbleached flour, 200 g freshly milled red fife, and 202 g multigrain flour. Let sit a couple of hours. 

4. Mix in 22 g salt, 266 g levain and 50 g water. I used pinching and folding to integrate everything. 

5. I do 4 series of folds 30 to 45 minutes apart and then I let rise until doubled. 

6. I divided the dough into four portions and did a quick preshape. I let it rest 10-15 minutes and then did a final shape. 

7. The dough was but into bannetons and covered with a plastic bowl cover. This is new to me. I usually use a large ziplock bag but I found these covers at the dollar store. They look like shower caps. They worked beautifully and are a lot less hassle than the huge bags that I have to dry out each week. 

8. The loaves proofed overnight in the fridge. I keep my fridge at 37F so it is quite cold.

5. 14 hours or so later, they were baked straight out of the fridge in preheated Dutch ovens (475F). After I load the dough, the temp is dropped to 450F for 25 minutes although the second batch was done at 475F because I forgot to drop the temperature. Then the lids come off and the loaves were baked for another 20 minutes at 425F. 

I want to thank MutantSpace for the inspiration! Crumb shot to come later if I remember!
