Instructions: Mix all dry ingredients thoroughly. Add water. Mix with hands until well- moistened but not sticky.

Divide into 4 parts, roll out each quarter until 1/4 inch thick, place on cookie sheet (each part should cover half a cookie sheet). Bake at 350 for 30 minutes. Score with a knife before baking, if desired. Break into pieces as needed. Keeps indefinitely in air-tight, moisture-proof containers.

Zip-lock bags are good for carrying hard-tack in a backpack.
