Rye kernel & flax seed sourdough

Made a couple of loaves today that went over well with the Taiwanese in-laws, and that I am pretty happy with.  My usual whole wheat sourdough base, with ~30% added high gluten white flour, and about 1 1/2 cups of rye kernels (soaked overnight, then brought to a boil and then left to soak another few hours) and about 1 cup of flax seeds (soaked overnight), and ~1+% salt.  Probably about 9 cups flour total, plus the extra seeds, making a couple of large loaves.  My sourdough, which I have been keeping in the fridge 100% of the time since coming to Taiwan, hasn't yet developed much of a sour flavour (which is fine with everyone but me), but is working well to leaven my doughs. 

This time, I started with ~3 cups of starter, adding 3 cups of flour the night before and putting in the fridge.  After letting that warm up in the morning, I added the final 3 cups of flour, along with the rye and flax.  Bulk ferment for another 2 1/2 hours, split, stretch, fold, shape, and proof for about another 2 hours.  As you can see, precise measurements and replicability are not too high yet on my priority list.  Will likely try this one again and actually keep track of masses...
