I make my jam in sterile jars and use a freezer jam recipe. I then seal using a hot water bath for 15 minutes. I know you don't need to seal it but I always do. Something about it makes me feel safer especially if you gift it and they don't freeze it immediately. My question is can I leave it in the pantry on the shelf since I did seal it. The jam was only "cooked" during the hot water bath.

  • Do you use a jam recipe made for canning? (I.e. without non-fruit additives like chia seeds.)

Only recipes from trusted sources should be used for shelf stable canning, as they are proven to produce a product with a sufficiently low pH to be safe when stored at room temperature.

The boiling water bath process is a way to create a vacuum seal, it is also a way to get the contents of the jar to near boiling for a certain amount of time, this will kill most microorganisms (any remaining will not be able to thrive in the low pH high sugar environment).

As you are not using a recipe specifically designed for a shelf stable product and you are not putting very hot jam/jelly into the jars prior to processing (you have no way of knowing how hot the center of the jam gets), your jam will not be shelf stable.
