Most of the time when I think of sour cream I immediately think of anything Mexican. Tacos, nachos, enchiladas, or whatever your favorites might be. I can’t have Mexican without sour cream.
Sour cream is actually a very versatile ingredient. It can be used in baking to make things moister, or in salad dressings, or sauces to make them creamier, just to name a few.
But the question is, how long does it last? Or, how can you tell when or if it’s gone bad? I’m going to dive into all of that.
Top 3 ways to tell if Sour Cream is bad
1. Use by date
Look at the date on the side of your container. It will have a use by, sell by and/or best by date on it.
- Sell-by dates are so the store knows when it should be sold by in order for the consumer to have time to use it before it spoils.
- Use By dates tells the consumer the lastest date that you should use the sour cream.
- Best if used by means that you are going to get the best taste, flavors, and quality out of it if you use it before this date.
Sour cream that has gone bad is going to have an unpleasant smell to it. Obviously, “sour” cream will have a little tangy smell to it already, but you will notice a sour smell when you open the container that is more of a rancid smell.
Smell in combination to any of these other factors below will tell you for sure if its safe to eat or not.
You will notice when you open your sour cream that there is some separation between the cream and the liquid. This is normal and can be drained or mixed back together before you use it.
You want to make sure that it isn’t overly watery or clumpy at all. Sour cream should be a smooth creamy texture when it is good.
4. How it looks
Again, you want a nice smooth creaminess to your sour cream. If you notice any mold on the top of it then discard it. Usually, you will see a green or white fuzzy mold on the top of the cream right when you open it.
Bacteria growth will show itself by color. If you see yellowing, that is also an indicator that your sour cream has spoiled and you should throw it away.
I always go by the “When in doubt, throw it out” method.
