Canning Pesto Sauce
Can pesto sauce be canned? if the sauce didn't pass through pressured can, is it safe to chill and store it for 2 to 3 months?
Since I have no experience with canning pesto I'll refer to National Center for Home Food Preservation.
"Pesto is an uncooked seasoning mixture of herbs, usually including fresh basil, and some oil. It may be frozen for long term storage; there are no home canning recommendations."
From this I'd say the only long term storage solution would be to freeze it.
