Recipe Notes
You can store the sauce any number of ways. I used glass jars filled about ⅔ of the way up. I let the sauce cool in the jars on the counter then put them in the fridge over night. The next day I put the jars in the freezer. Make sure you leave enough room at the top to allow for expansion during freezing so you do not break the jars.
