Recipe:
2 cups whole wheat flour
1 cup dried fruit bits
1/4 lb brown sugar
1-1/2 ounce dried milk powder
1/4 tablespoon baking powder
1/4 tablespoon salt
1/4 cup honey
1/4 cup dark molasses
1/4 cup vegetable oil such as canola
1/4 cup wheat germ
1/2 cup water
1 tablespoon sesame seeds
Mix everything together in a large bowl. The first time you try this, you will have a hard time getting it to mix on only a 1/2 cup of water, so you may have to add slightly more. However, mixing it wetter will lead to possible spoilage.
Preheat a 300 degree F oven. Note that this is not as hot as most baking recipes.
Turn the mixture into two greased 8×8-inch cake pans and spread it as evenly as possible. Bake for one hour. Remove from the oven, let cool for five minutes, and then invert the pans to remove the bread. Cut each bread loaf into 16 squares. The proper consistency is not rock-hard, and it is a little chewey.
Stack and air dry the squares for 24 hours. This gets rid of much of the excess moisture that might lead to spoilage. Store the squares in plastic sandwich bags and squeeze out as much of the air as possible. I normally get six squares into each sandwich bag, so the whole batch will require five or six bags, minus however much you ate during the cutting.
If you make this relatively dry, it will keep for months. It is best when eaten within a month or two. Refrigeration is unneccessary.
Most of my variations are with the dried fruit. I can do this just with raisins, but it is fun to try to do it with five or more types of dried fruit like apricot bits, cranberry bits, blueberries, etc. Try not to use dry fruit bits much larger than raisins, and make sure that the fruit is dry before it ever goes into the mix. Fresh fruit is not acceptable. This has no egg, yeast, or whole milk, so there isn't too much to spoil. If mold does grow on the bread, that is your sign that you used too much water in the mix.
I've done some trips where Logan Bread was 40% of the total food.
