Hardtack Mold

For some random reason, I decided to make some hardtack. Simple stuff, in it's most basic form made from only water, flour and salt. Keeps literally forever as long as it's kept dry, even if it it doesn't necessarily contain much in the way of actual nutrition. Also known as 'ship's biscuit'. Traditionally, hardtack is soften in water, or a beverage such as coffee. However, it seemed to me that if it were in smaller, bite-sized pieces, it could be softened in the mouth, possibly in the manner of a jawbreaker. And that's what this mold is for. It is intended to be used in the fashion of a cookie cutter to cut out an approximately 3"x3" square of dough, at the same time scoring it into 36 bite-sized pieces that can be broken off and consumed one at a time, no dunking in coffee necessary. Naturally it can be used for other substances as well. It was thrown together a bit quickly, as you can see if you examine the fine details, but there are no imperfections that compromise its functionality.

It should be noted that solidified resin is not necessarily the best material to use in food preparation and is most definitely not recommended for that purpose. I'm not personally overly concerned; but before using any 3d print in connection with food, be sure to research the toxicity of whatever it is you use for printing.

Hardtack recipe (basic):
3 cups white flour
1 cup water
1 tsp salt
Optional: small quantities of vitamin powder, extra salt/pepper, dried bean flour, spices- anything with zero moisture and no fat, substituted for part of the flour.
Mix together, roll out on floured surface about 3/4 inch thick. Divide into approximately 3 inch squares (or cut out using this mold) and a few holes with a fork. Bake in oven on 375 degrees Fahrenheit for 30 minutes. Turn and back other side for 30 more minutes.
To get it really dry, reduce oven temperature to 150-200 degrees Fahrenheit and bake for a further one to two hours.
for long term storage, vacuum seal, with food-safe desiccant if desired, while still warm but not hot.
