In a large bowl, combine the flour with ½ cup of the water. Stir until a shaggy dough forms. Add the remaining water one tablespoon at a time just until the dough holds together—do not over-hydrate. Knead the dough until smooth, about 15 minutes. Divide into 6 equal pieces.
Shape each piece into a ball, then flatten and roll into ½-inch thick rounds resembling English muffins. Place on a lined baking sheet. Poke small holes over the tops like a cracker.
Bake for 3 hours. The biscuits should lift cleanly off the sheet. Reduce oven temperature to 200°F and bake for an additional 3–4 hours until rock hard.
Let the biscuits cool completely before storing. To eat, soak in liquid or break with a tool before using in stews.
Notes
These biscuits are too hard to eat plain and must be softened in water, beer, or broth before consumption.
Ideal for historical reenactments, prepping, or educational culinary projects.
Store in an airtight container in a dry, cool place—they can last for years.
