This is the only bread we eat in my house now....it is super easy to make & very inexpensive. I use 100% stone ground whole wheat bread flour tho. I also put things like flax seeds & hemp hearts in it to make it more of a multigrain. I use a mini muffin tin & make mini loafs for Felix .....he never liked store bought bread that I bought but he gobbles this up so quick it is gone before I know it....
