Duane - I've altered the original Logan bar recipe, too, and have packed in more fruit and nuts and less liquid to begin with so it doesn't need so much baking and drying time. I haven't tried adding eggs, however. That might be next! That's the fun part about recipes... once the concept is understood, in this case fruit, nuts, and seeds and some way to bind it all together, the sky's the limit for tweaking for personal taste.
From what I've read, the people who came up with the original recipe were looking for a way to pack in the calories. To me it seems they missed the concept of calories, because there is very little fat in the recipe, and that's where the calories are most dense (9 calories per whatever instead of 4 calories per whatever in carbs and protein). That's ok with me, though, because the Logan bread is still a good idea and my substitute for energy bars. Not to mention it led me to promoting my fruitcake to trail food!
