Even though store bought dried goods will last for a couple of years, chances are within a certain length of time weavels and other bugs will get into them and they will begin to taste stale. Oven canning these goodies will preserve them for long periods of time, which is awesome for the emergency prepper, like myself.
Here is a rundown for the process of oven canning.
What you need:
Dried goods (rice, pasta, cereal, dried fruit, dried vegetables, dried herbs, etc)
Canning jars of any shape or size
Canning lids to fit the canning jars
Step 1: Preheat oven to 200 degrees.
Step 2: Place cookie sheet into preheating oven.
Step 3: Fill jars with dried goods, leaving the lids off
Step 4: Place jars on cookie sheet in the oven for 1 hour.
Step 5: Remove carefully from oven. Take a damp paper towel and wipe the mouth of the jar with it. Place lid firmly on the jar.
Step 6: Listen for popping to indicate that the jar has sealed. As in regular canning, not all jars will seal. If the jar does not seal it could be an indication of a bad lid or a bad jar or just plain dumb luck. You can try it again for that jar or be satisfied in knowing that at least your dried goods are kept safe from bugs.
Another little nifty trick for those that do not want to preserve their dried goods for long periods of time, but would like to keep the little critters out is to put bay leaves in their jars and bags of dried goods.
