There was such a thing. I did some research. One kind of Hunza
(meaning raisin) bread had raisins such as this type. The other type
was supposedly a kind of bread (very different that was eaten by Hunzas
and you would lose weight). It appeared to be a kind of heavy flat
bread that if you ate it, it would be very nutricious and you would be
completely filled up and not hungry for hours. I did get the recipe.
I never got around to making either kind but it would be fun to hear if
anyone did!!!
