I believe there is a serious error in this recipe. Perhaps it should call for 2 Tbsp water instead of 2 cups? I had to add at least another 1 1/2 cups flour to get it to a kneadable stage. Not sure if it will turn out!
I don't think anyone would have done it, but the preheating mentioned in step 1 is much too early. The dough mentioned in step 4 was a batter. So I added enough flour (5 1/2 more cups), extra salt (1 teaspoon) and some oil (1 tablespoon - just because) to make a kneadable dough. I continued from there, and got 2 medium loaves (620 g each) and 17 rolls at about 45 g (1 1/2 oz) each. What can I say? The bread is delicious, but it's not really the bread of this recipe. And I'm not sure what the buckwheat flour contributes - maybe some texture, not much flavor what with the caraway seeds. We will eat the bread and enjoy it, but I don't think I'll try this again.
