Gruel Dehydrating

http://www.durgan.org/URL/?EQCFK 29 November 2014 Gruel Dehydrating.
An experiment was made by dehydrating some recently made gruel. The end product would make a fine home dry cereal for camping or daily use. It is dry enough to keep for relatively long periods at room temperature. Process is to place on a tray and dehydrate for about eight hours at 145F.The powder is vacuum packed. I store mine in the freezer, since I won’t be using it for some time.

Sound like hard tack made from an assortment of grains. A difference is that hard tack is baked.

Hard Tack:
Wheat Flour
A bit of water to make a dough
A pinch of salt
Roll to fit the pan being used.
Bake until it starts to take on a bit of color.
Cut into biscuit sized pieces.
Let it cool for a day.
The next day, bake it again to remove all traces of water.
You can feed an army with this stuff.

You are so right. I also make hardtack. It sure has to be dry to store at room temperature for long periods. The gruel is just another storage method. Diversity if you like.
