If you store it in an airtight container in the fridge, your cranberry sauce can last for up to two weeks. But, if you're feeling extra fancy and decide to can it, it can last for months! Just make sure to follow safe canning practices, or you might end up with a jam that's more mold than magic.
Now, you might be thinking, "But what about freezing it?" Well, my friend, freezing is a great way to preserve cranberry sauce, and it can last for up to a year in the freezer! Just make sure to store it in an airtight container or freezer bag, and you'll be enjoying that sweet and tangy flavor all year round.
So, how do you know if your cranberry sauce has gone bad? Well, if it's developing an off smell or slimy texture, it's time to say goodbye. But, if it still smells and tastes like cranberries, it's probably still good to go! Just remember, when in doubt, throw it out, and make a fresh batch – after all, fresh is always best.
