How To Make Sour Cream

There’s nothing worse than being in the middle of a recipe that calls for sour cream and opening up the tub only to find it’s almost empty or worse- there’s mold all over it. Luckily, if you’re out of sour cream, you can make your own! All you need is two ingredients and a lot of upper body strength. (I’m exaggerating about the need for muscle tone. I can do it, and I haven’t worked out since the 90s.)

What is sour cream?

First things first- there are two types of sour cream: cultured and acidified. Without getting too sciency, cultured sour cream is made with bacteria, while acidified sour cream is made with an acid. Fun fact: many store-bought sour creams aren’t made from cream at all. They’re made with milk that’s thickened with artificial ingredients. Homemade sour cream doesn’t have artificial thickeners so it will be a little runnier than what you’re used to, but the flavor will be spectacular!

Making Sour Cream From Scratch

Since you probably don’t have a vial of lactic bacteria in your pantry, you’ll need heavy cream and an acid. I like using vinegar, but you can also use lemon juice or buttermilk. You’ll also need a mason jar or another air-tight container. To make sure the container is squeaky clean, boil it for a few minutes, let it cool, and then add your cream and acid. Then cover and shake it (or blend it) until it thickens. That’s it. You’ve made sour cream.

To Ferment Or Not To Ferment

I’m a pretty impatient person, so if I’m using the sour cream for a batter or a dip, I add it a few minutes after I’ve made it because its primary purpose is to add creaminess and flavor. It’s not the star of the show; it’s a background singer. (Like the one chick in Destiny’s Child whose name no one ever remembers.) Now, if it’s the Beyonce of your dish, you’ll want to let it sit for a day on your counter to let the cream ferment and thicken and then refrigerate. To keep it 100, I usually skip fermenting it and just put it in the fridge to thicken overnight. It still tastes great.

How long does it last?

That depends on you. It’s best to store the sour cream in the back of your fridge, not the fridge door, where temperatures fluctuate. If you clean your container well and keep the sour cream at 40 degrees, it should last about two weeks. To keep it fresher longer, store it upside down so it isn’t affected by air. When the cream falls to the lid of the jar, it creates a vacuum, which slows down mold and bacteria growth. You can use this nifty trick on all dairy products that come in a container or a jar. I’m looking at you, cottage cheese.

Some of the things you can make with sour cream

Don’t limit your sour cream to just a topping for baked potatoes or a heap of nachos. It works magic in all sorts of dishes. You can use it in sweet and savory preparations to add tang, moisture, and tenderize. It’s the little cream that could.

How To Make Sour Cream

If you’ve run out of sour cream and don’t want to run to the store for more—you can make it at home with just two ingredients: heavy cream and vinegar!
