In all of the videos I saw, quart canning jars were used. Because there is only one person living here, pint jars seemed like a better choice. I filled 6 wide mouth pint jars with crackers - 2 with cheesy crackers - 2 with oyster crackers - 2 with Ritz crackers. I wiped the rims to remove any crumbs and added lids and rings.
The majority of the directions said to put the jars in a cold oven, using a cookie sheet to hold them. Then turn on the oven and set it for 250 degrees. When the oven gets up to the correct heat, set the timer for 30 minutes. When the time is up, turn off the oven and leave the jars in it until cool.
So I did. Five jars sealed and one did not. Only time will tell if the seals will hold. I'm going to set the sealed jars aside and check the seals now and then. If they hold, this is an excellent way to store crackers. I can't say yea or nay on this one yet. If any of you have used this method to store crackers, please let me know.
My grocery order today included several items for a few more food preservation experiments. I will let you know how the next one turns out.
