Q. Is this a safe practice or not to turn jars upside down?
A. Turning jars upside down after putting the lids on was once an accepted method, especially for jams and jellies… the heat from the jelly supposedly heated the lid, ensuring a good seal. The current school of thought is that this is no longer a safe method for sealing jars as it can cause food to be trapped underneath the lid causing possible seal breakage… it’s now recommended to process in a boiling water bath instead.

Q. I have some old recipe and canning books, can I still use the recipes for canning?
A. As long as all the ingredients in the recipe are cannable (some ingredients aren't!)…
Use the ingredient in a recipe (even in outdated books) that takes the longest processing time (according to recent standards) and follow those instructions.
