3-Days of Marching Rations

[Kegluneq]

That bread looks good, you got a recipe?

Some flour
Some salt
Some water
Mix
Bake until golden
Lose all your teeth trying to eat it...

Bucellatum is a pretty masochistic foodstuff, but it's very easy to make. I found it was best soaked (in black coffee, if you're going for the Civil War era hard tack), then fried until soft-ish. I think it can be made soft enough to bite and chew normally if you add olive oil though, which I assume Mithras has done as they look too large to be manageable otherwise. The only problem with adding oil is that the hard tack will go off much quicker.

There is no mention of dried beef (beef jerky), but would it not be feasable this was also part of the rations?

In this vein, meat could also be salted and thus dehydrated. That would presumably make it a lot easier to carry, although it would have to be soaked before cooking.
