Rustic bread test run was successful. I used 2.2 kg scale. Base of recipe was same dough as country bread but this time bread has 20% whole-wheat (10% rye, 10% hard red spring wheat). I have to thank Larry about his YouTube video where to said to shut vents after 10 minutes, the bottom of crust was perfect. Very happy with taste. This bread delicious on own and can be eaten with other dishes.
