I looked at the recipe and think it looks good. It must be part of some popular eating plan these days.I think maybe she brought it in as a snack and it turned out to be awful. Maybe she hadn't tried it before. I don't think she wanted it which is why she offered it up for others.
As it turns out, I think it is something called "Nordic Stone Age Bread" or some variation of that. It appeared to be comprised primarily of one uniform seed though, I think pumpkin seeds. Honestly, it looks like someone baked a loaf of bird food.
