Canning Crackers for storage

Place in a cold oven and do NOT let the jars touch. Use the middle rack if possible. Set the oven to 225° F. and use the following time table:
Start timing when the oven reaches the desired temperature.
Pints - 20 minutes
Quarts - 30 minutes
Half Gallons - 45 minutes
Tighten the lid on each jar, being careful not to get burned, and set on a towel to cool. The shelf life of these items is about 10 years if stored in a cool, dry place.
