Got Cream? Make Cultured Butter!
Mar 18 | Written By: Sabrina Huizar
POV: your kitchen just got deep cleaned.
Everything is spotless. Counters gleaming. Sink empty. Floors shining.
And naturally, the very next thing you decide to do… is make butter.
I wish I could explain why I am the way I am, but fermentation people will understand. When ingredients start whispering that they’re about to turn, the only logical response is to culture them and see what happens.
In this case, I had a container of cream that was getting ready to quit on me. Not spoiled. Just… thinking about it. Culturing it would buy me a couple extra days to decide what to do with it.
Turns out the answer was obvious.
Butter has entered the chat.
What Is Cultured Butter?
Cultured butter starts with cream that has been fermented before churning.
Instead of simply whipping fresh cream until it separates into butter and buttermilk, a culture is added first. The cream sits for a period of time while beneficial bacteria ferment the lactose and produce lactic acid.
That fermentation changes everything.
Cultured butter develops:
• a deeper flavor
• a slight tang
• more aromatic complexity
• a softer, silkier texture
The result is butter that tastes less like plain fat and more like a finished ingredient.
It’s the difference between something that spreads on bread and something that elevates bread.
Non-Cultured Butter (Sweet Cream Butter)
Most butter sold in the United States is sweet cream butter, meaning it is made from fresh, uncultured cream.
The process is simple:
Fresh cream is churned.
Fat separates from buttermilk.
Butter is washed and salted.
Sweet cream butter tastes clean, mild, and creamy. It’s great for baking and everyday use, but it doesn’t have the depth of flavor that fermentation creates.
Cultured butter, on the other hand, carries subtle yogurt-like notes, gentle acidity, and a richer aroma.
French Butter vs American Butter
If you’ve ever tasted European butter and thought why does this taste so much better?, there are a few reasons.
Higher Butterfat
European and French butters usually contain 82–86% butterfat, compared to the American standard of about 80%.
That extra fat creates a creamier texture and richer flavor.
Culturing
Many traditional French butters are made from cultured cream, which gives them that signature tangy depth.
Slow Churning
Traditional butter-making methods are often slower and gentler, producing a smoother texture.
The result is butter that feels luxurious, spreadable, and deeply flavorful.
Homemade cultured butter brings you surprisingly close to that experience.
Why I Cultured My Cream
My cream wasn’t bad yet, but it was getting close to the point where you start giving it the side-eye.
Culturing it was the perfect move.
The bacteria begin consuming the lactose and producing lactic acid, which slightly lowers the pH. That extra acidity helps stabilize the cream and gives you a little extra time before spoilage takes over.
Translation: fermentation buys you time.
After letting the cream culture overnight, I still hadn’t decided what to do with it.
But once the mixer gave me a wink, the decision made itself.
Butter.
How to Make Cultured Butter
Ingredients
2 cups heavy cream
1-2 tablespoons cultured crème fraiche. You can also use yogurt or kefir.
Salt to taste (optional)
Optional additions: garlic, herbs, citrus zest, honey
Step 1: Culture the Cream
Stir the culture into the cream.
Cover loosely and leave it at room temperature for 12–24 hours.
The cream will thicken and develop a mild tang.
Step 2: Chill the Cream
Place the cultured cream in the refrigerator overnight before churning. Cold cream churns more efficiently and the flavor will deepen.
Step 3: Churn
Pour the cream into a stand mixer fitted with the paddle or whisk.
Whip on medium-high speed.
Stages you’ll see:
Whipped cream
Overwhipped cream
Sudden separation into butter solids and buttermilk
