I like to give jam as gifts and it would be neat if i could put peanut butter with it inside the jar. Is this safe or not? Thank you for your time. :)
Commercial peanut butter is shelf stable for several months in your pantry, however it is not acidic enough for home canning. When you remove most of the air in home canned goods you are actually setting up a good environment for botulism to grow. Botulism can’t thrive in an acidic conditions, that is why a low ph is essential for safe home canning.
