    Step 1 - Gather Your One Pint* Canning Jars

    Start with clean, dry one-pint canning jars. Be sure to follow the washing instructions on the canning jar box. If re-using jars, be sure to use brand new lids and seals. You'll need 6 jars for the batter of one 2-layer recipe.

    * Wide mouth 1-pint jars will work best when trying to "dump" the cake out.

    Special Note:

    Thanks to Scooterskitten in my Desserts and Baking Forum for giving me the idea for perfect teacher gifts. Scooterskitten bakes cakes in canning jars to send as care...MORE packages to her husband in Iraq. She told me that he often shares them with the other soldiers who happen to be having a bad day. Her latest posting is about how her husband traded one canning jar cake for two monster coffee energy drinks. She said that monster coffee energy drinks are like gold over there. I guess these cakes are quite valuable, too.

    She called hers Pirate Cakes.

    Step 2 - Grease the Jars

    Using a spray oil, completely cover the inside of the canning jars. Preheat the oven to the temperature as directed in your cake or quick bread recipe.

    Step 3 - Use a Baking Sheet

    A baking sheet, with sides preferred, is needed to support the canning jar cakes in and out of the oven.

    Step 4 - Add Batter to Jar

    Use a 1/4 cup scoop to add the batter to the jar. Any batter that sticks to the side, wipe out. Fill the jars to just under the 1-cup mark.

    Set your timer for 15 minutes less that the time stated in your recipe. I used a bamboo skewer to test for doneness. Bake longer, if necessary.

    Step 5 - The Baked Cake

    No matter how precise I thought I was being, I could not get all of the cakes to come out exactly the same.

    Step 6 - Covering the Jars

    For the jars to seal themselves, the jars must still be hot. The lids should also be at least room temperature. Sit them on the stove, if necessary. Don't screw on the caps too tightly. Within 15 minutes of capping the jars, you'll hear popping. This is when the heat from the jars cause a vacuum making the jars airtight.

    Step 7 - Decorate

    To decorate my jars, I used a 10-inch square of fabric cut with pinking shears. I put it on with a rubber band. I printed some business cards with a photo of pomegranate, the cake's name, ingredients and a note from my daughter to her teachers. I used a hole punch to make a hole in the upper left corner of the card. I tied one knot in the cord and then threaded the card on top of the knot. I then tied another knot to secure the card.

    If using new jars, be sure to keep the canning jar box. It...MORE is perfect for holding the jars for distribution.

    If you plan to use your cakes for care packages to the Middle East or to mail them anywhere else, wrap the jars in bubble wrap and then place tightly in a mailing carton. Seal the carton as usual.
