We do not recommend oven processing for the following reasons:
1. Variable heat in the oven could cause jar breakage.
2. Food located in the center of the jar does not always reach safe internal temperatures
3. The possibility of damage to the sealing compound is high in the oven.
While foods may be fully cooked in the jars, they are not safe for shelf storage. Jarden Home Brands does not feel sufficient research has been completed in this area and does not endorse the baking procedure.
Information for canning high acid foods is available on our website at www.freshpreserving.com.
