If canning is not your jam, you will need to freeze it. If you freeze in glass jars, make sure to leave a minimum of 1" headspace for expansion as the liquid freezes. Another option I regularly use that takes less space in your freezer is these Food
Storage Trays. I use the 1 cup, 1/2 cup, and 2 tablespoon trays. If I didn't can my stock, then I think the 2 cup tray would be very useful. Once the food freezes in the tray, I take the food out of the tray and store it in either a reusable bag or a glass container in the freezer.
