Canned Cranberry Sauce can go bad eventually but it would take at least 10 years or more before the canned cranberry sauce went bad.
The canning process of the canned cranberry sauce helps preserve it.
As long as the can of cranberry sauce is not open it will last for up to 10 years or more but once opened the canned cranberry sauce will only last for up to a week before it goes bad.
Once opened the cranberry sauce should remain refrigerated if not using it within a few hours to prevent mold and bacteria from growing on it.
I prefer to warm up the canned cranberry sauce before serving it or eating it.
I've eaten cranberry sauce cold before as well and it was okay.
I've also made cranberry sauce sandwiches by taking a few slices of bread and putting some cranberry sauce between them.
It made for a great sandwich.
Even eating the cranberry sauce right out of the can is good.
Some people warm up canned cranberry sauce and some people just serve the canned cranberry sauce cold or at room temperature right out of the can.
You can serve the canned cranberry sauce either way.
My mom would warm up canned cranberry sauce before she served it and my Grandma always served the canned cranberry sauce cold.
It's all up to you and is a personal preference.
If you prefer the canned cranberry sauce warm then warm it up but if not you can serve it cold or at room temperature.
Cranberry sauce is usually served cold or chilled.
But if you want to heat the cranberry sauce up you can do so.
I like my cranberry sauce heated up so that it's warm but not too hot as it tastes better than being chilled or served cold.
However I do sometimes like to make cranberry sauce sandwiches by placing cold cranberry sauce out of the can onto some bread and eat it that way.
But when you eat cranberry sauce for Christmas or Thanksgiving dinner it's traditionally served cold or chilled but it's okay to eat it warmed up if that's the way you prefer it.
