In a small bowl, mix together the warm water, honey, and yeast. (I heat my water to 110°F) Let the mixture sit for 10 minutes until the yeast creates a bubbly foam on top.
Meanwhile, take a large bowl and mix the buckwheat flour, all-purpose flour, and salt together.
Then in another small bowl, beat the eggs together with a fork and set aside.
Once the yeast mixture is ready, pour it into the bowl of dry ingredients. Then add in the beaten eggs, olive oil, and lemon juice. Stir together with a large spoon until all ingredients are well mixed.
Cover the bowl and let it sit in a warm place for 50 minutes, allowing the dough to rise.
Preheat the oven to 375°F and lightly oil a bread pan.
After the dough has risen for 50 minutes, pour it into the oiled bread pan. Bake it in the oven for 43-45 minutes or until the top has browned nicely and an inserted food thermometer shows at least 190°F.
Let the bread cool.
