Imagine waking up in the morning to a sweet blueberry jam breakfast. Are you tempted? The blueberry jam without pectin can be prepared easily from scratch with only 2 ingredients. Just make sure to use always sterilized clean jam jars when canning the jam. We add some rum into the lid before closing the jar as this prevents mold and preserves the jam much longer naturally. Print and use the jam labels from this post to decorate your jars.
