I just made marinara sauce yesterday, sauced some pasta with some and put the rest in a mason jar. How long can I expected this to stay fresh? It's completely sealed-off in a mason jar, I used canned tomatoes and fresh ingredients to make it.
Also, was just making some fresh pasta and accidentally pre-heated all of the marinara in the microwave enough that it began steaming: can I seal-off any that I don't use and save for a later date?
For reference, Marinara and/or Tomato Sauce is not listed in the "storage guide."
