I splurged and bought some Weck jars for canning. I purchased the .5 liter tulip jars. I notice that they have a substantially larger mouth than Ball/Kerr jars. They also appear to be both fatter & shorter. I tested with my canner, and can get only 5 jars per level instead of 6 jars with the Ball pint jars.
Does the difference in shape mean any changes I should adjust any recipes from the Ball Canning book? I am particularly wondering if the head space should remain the same.
