Once you have tried your first batch of Logan Bread, you will know how you want to modify it for your own tastes. You can make it drier if you want it to last longer. I've eaten Logan Bread that was six months old, and it was simply in a ziploc sandwich bag. If you make it too dry, you will break a tooth on it.
Some people like it with more nuts. Some like it with their favorite dry fruit. Some people use more cooking oil to make it seem moister.
Do not use fresh fruit.
