While it may seem like a good idea, this is not a recommended practice.
For example, to take a commercial salsa and re-can it into smaller jars can lead to some issues. They include:
- It is unknown what the original processing method or time was for the product.
- The original label and information is no longer there.
- If ingredients and allergens are not noted, someone could have serious health complications.
- If the original product is subject to a recall, how would these be traced?
- Re-processing will also negatively change the texture and flavor.
A better option is to contact the original company to see if they offer smaller sizes or gift options. A small business may be able to accommodate these requests.
