What is Sour Cream? 

How Long can You Leave Sour Cream Out

Sour cream is basically a dairy product popular across the Globe. The famous spread or dipping is prepared by fermenting regular cream. This fermentation process is solely done by using lactic acid bacteria. That is precisely why sour cream tastes like a mixture of sour and sweet tastes. The name of sour cream has come from bacterial fermentation because the process is also called souring. 

The sour cream is a relatively thick inconsistency because the bacterial that enters or is cultured thickens it. 

Earlier the traditional way of preparing sour cream was somewhat different from now. Then, it was prepared by fermenting the cream that skimmed off at the top of the milk. The pasteurized cream can also be converted into sour cream by the lactic acid bacteria culture or other acid-producing bacteria.

Health Benefits

Sour cream is not only delicious and mouth-watering but also has some beneficial health values. People might think about how a fermented food or sauce or something can be good for health. But, exactly because of this confusion, people always avoid these food items from their health-conscious diet chart. 

In this section, the food values of sour cream will be discussed thoroughly. So, in case you are one of those conscious people, you must have a look.

Sour cream is technically different from other regular dairy products. By difference, we mean both the differences of taste and composition. This popular spread or cream consists of multiple beneficial components. 

Sour cream has fat, carbohydrate, protein, calcium, phosphorus, magnesium, potassium, Vitamin B12, Vitamin A, and Vitamin B2

  • Absorption of fat-soluble vitamins

Some specific vitamins need a source of fat for absorption in the digestive tract. These fat-soluble vitamins include Vitamin A, D, E, and K. People may be affected by cancer, diabetes, and multiple immune disorders if they lack these vitamins. 

Vitamin A, D, E, and K can be found in fresh fruits and vegetables. Hence, eating them will help gather vitamins A, D, E, and K. But the problem here is that none of these vitamins provide fat on their own. So, an external source of fat is always needed. 

Regular sour cream primarily consists of fat. Therefore, sour cream may act as the source here.  

  • Contains probiotics

Probiotics are living microorganisms that help us with digestion. Probiotics also help in keeping our healthy life intact. It also increases the immunity power when consumed. 

Since sour cream is produced by souring or fermentation, most manufacturers bring it after pasteurization. Meaning all the bacteria in the sour cream are destroyed before packing and selling. This step is taken to lower the problems regarding food poisoning. 

However, after pasteurization, some manufacturers add a limited amount of probiotics to the sour cream to obtain probiotic help.

  • Low in carbs

This can be one of the principal reasons why people choose sour cream. Since sour cream is low in carbs, it might help people with their diet. There are many types of diets. Among them, one of the most popular diets is a carbohydrate-free diet. Some examples will be the Keto diet and Atkins. So, these people may intake sour cream without any hesitation. 

Dangers of Consuming Unpasteurized Sour Cream

In the previous section, we spoke about the benefits of helpful microorganisms in unpasteurized sour cream. But, there is another significant problem that you should be aware of.

Unpasteurized sour cream is not safe for all people. The unpasteurized version indeed contains many beneficial bacterias. But along with it, stay some troublesome microorganisms as well. This can be fatal for some people, especially pregnant women.

Raw dairy products contain Listeria in them. This can cause serious harm to the child. It can cause death in an extreme situation. Along with the child, the mother can also be affected by the bacteria. So, it is advised for pregnant mothers to stay away from unpasteurized sour cream and all raw dairy products. 

Some other harmful microorganisms found in raw dairy products are E.coli, salmonella, and many others. These are actually fatal for our stomachs. Diarrhea, vomiting, stomachache, and many other complications may form from these microscopic criminals. 

So it is better to stay away from unpasteurized dairy products, including sour cream.

How long can you keep sour cream intact?

Now, we have come to the crux of the topic. Sour cream, as the very name observes it, has a distinctive sweet and sour taste. Well, the question here is, can sour cream go…umm…SOUR?

Sour cream is indeed a delicious dairy product obtained by fermentation or souring. The acid-producing bacterias are added to the cream, and then the sour cream is produced. But, as you know, sour cream contains bacteria. The edible sour cream consists of bacterias like Streptococcus lactis and Leuconostoc citrovorum. These microorganisms are safe for human consumption.

However, sour cream might form mold and yeast if kept out of the refrigerator for too long. If the sour cream has cultivated all these, it is not safe to eat the cream. Now, the question is, how long is the time being that sour cream is safe to eat?

Well, generally, it is recommended by many people and kitchen enthusiasts that keeping sour cream out is never an option. No matter the packaging state (opened or unopened), sour cream should always be kept in the refrigerator at less than 40 degrees Fahrenheit. That means you should continuously switch on your refrigerator if you are keeping sour cream in it.

And if it is intact and stored in the refrigerator, you might use it for up to three weeks after the sell-by date. On an average count, sour cream is edible for seven to twenty-one days from the manufacturing date if it is kept at 40 degrees Fahrenheit in the refrigerator.

Let’s suppose you want to keep your sour cream out of the refrigerator. Therefore, the question that comes first into the context is, how long can we store it out? 

Personally, I will recommend you not to keep it out for even a moment. But if you are stubborn, let’s get straight to the point. Since sour cream consists of bacterias and there is a fair chance of some harmful bacteria to form, keeping it out for one to two hours between 40 to 90 degrees Fahrenheit will be enough because, by that time, the sour cream will successfully be spoiled.

Even if it looks intact after one or two hours of keeping it out, do not try to use it or eat it. Serious health issues may be caused by it. 

How to understand spoilage?

There are some easy ways and signs with which the spoilage of sour cream might be pointed. Do check these points before eating the sour cream.

  • Check for the odd smell first. Fresh sour cream will have a delicious smell that compels you to taste a scoop. But, if it is spoiled, the smell will not at all please you. Rather you might be disgusted by the smell. If the smell from the spur cream is moldy, stinky, or anything that does not match the normal standard, guess what? It is time to throw it away.
  • Another visual sign is the growth of mold in sour cream. Often the improper storage of sour cream leads to this problem. You will see a sponge or velvet-like lair on top of the sour cream if mold has grown. The common problem is that some people scoop out the mold from the outer lais and start eating the same sour cream. Do not do that ever! This may lead to serious health hazards. So, in case you notice a lair of mold, take the package and throw it away. 
  • Well, there are enough visual points to understand if the sour cream is destroyed. First, try to monitor the color of sour cream. Generally, sour cream is white when fresh. But let’s say you see an off-color or a yellowish tint to the white texture. That is probably the indicator of spoilage. However, there are cases where yellowish sour cream is edible, and people have enjoyed eating that. But I suggest you straight away throw it.   

DIY sour cream

How Long can You Leave Sour Cream Out

Commercially packaged sour cream is okay to bring. But what if you yourself can make it at your home with the simplest ingredients? That is indeed smart. And if you’re one of those enthusiasts, let’s know a bit more about the recipe and preparation. 

For preparing DIY sour cream, you will need

  • Milk
  • Cream
  • A jar
  • Fresh lemon juice

And now, let us move on to the procedure of preparing sour cream.

  1. First, take the jar. Now, this jar should be clean. Also, do not choose a jar that has a 5l capacity. A medium one will do the job. Now, take 1 cup cream and heat it thoroughly. Do not burn the stuff. Rather, take it to a warm state. After that, cool it down and bring it back to room temperature. You may use raw cream as well. For that, I recommend you use a sour cream starter for it has a strong, active culture.
  2. Take 1/4 cup of milk in the clean mason jar. Now the next step is ‘lemon squeezy.’ take two teaspoons of lemon juice and add it to the mason jar. Give the jar a good shake. You might use vinegar as well at this point. But many people do not like vinegar in the DIY sour cream process because it has a strong flavor and smell that might ruin the taste components of sour cream.
  3. Open the lid of the jar and then add the room temperature fresh cream to the jar. Tightly close the lid and again give it a good shake. Once the shaking part is done, open the lead, cover it with a paper towel or kitchen towel, and let it sit. A pro tip for you here: do not seal the mason jar. Rather let it breathe. Hence, take a plate, paper towel, or kitchen towel for covering. Let the jar sit overnight. Make sure you are placing the jar in a warm place, not an oven, though!
  4. After 12 hours, you should see a thick layer of cream on top of the jar. If you want a thick cream, scoop out the upper layer from the jar. And if you prefer the consistency to be a little light, take a spoon and stir the cream well. And BOOM!

Sour cream is ready to serve. This DIY cream will stay intact for almost two weeks if kept well in the refrigerator. 

Sour cream substitutes

It is always better to be prepared for mishaps. For example, suppose you run out of sour cream all of a sudden or let’s say the sour cream is spoiled. What to do then? Are you going to throw your food away?

No way! Be smart. Stop worrying, start finding. Every ingredient in this world has a suitable substitute. Let us know then what can be the substitutes for sour cream.

  • Greek yogurt

The yogurt itself is the best substitute for sour cream. But the difference is about the consistency and also some of the components. While normal yogurt has a semi-liquid texture, Greek yogurt is somewhat near to the consistency of sour cream. Also, it goes well with dressing, topping, dipping, and spreading. So, people may choose greek yogurt instead of sour cream.

  • Cottage cheese

Cottage cheese is another healthy replacement for sour cream. While yogurt and sour cream are high in fat, cottage cheese is a low-fat, high-protein substitute. In addition, this dairy product has a soft and mild creamy texture that makes it an excellent choice for many people. So this can also be used as a substitute. 

  • Crème Fraîche:

Crème Fraîche is another dairy product, very similar to sour cream. This is made by adding a bacterial culture to heavy cream. The consistency and thickness of Crème Fraîche are similar to sour cream. Also, the taste of this product is a little less tangy. However, this is much higher in fat and calories than cottage cheese, greek yogurt, or sour cream. So, despite being delicious, it might not be the best choice. But its fat density makes it ideal for soup.
