This is my favorite whole wheat bread recipe and it comes out perfect every time.
Whisk together 2 1/4 tsp. yeast with 1 1/4 cups of warm water.
Add 1 1/2 tsp. salt & 1/2 tsp. lemon juice. Then add 2 Tbsp. olive oil and 2 Tbsp. honey. Whisk well after each addition.
In a Kitchen Aid mixer or by hand, mix in 1 1/4 cups whole wheat flour.
Add 2 1/4 cups all-purpose flour or bread flour and mix well.
This wasn't part of the original recipe but I add in 1 Tbsp. flax seeds and 2 Tbsp. sunflower seeds. Continue mixing until the dough is smooth and elastic. If you are doing this by hand, this is the point where you turn it out onto a floured board and knead until smooth and elastic.
Place in a well greased loaf pan, cover and let rise in a warm place until double, about 45 minutes.
Bake at 350 degrees for 35-40 minutes.
