What is Crème Fraîche?
Origin and Definition
- Crème fraîche, a type of dairy product, is a thick and creamy version of sour cream that originated in France.
- Its name literally translates to “fresh cream” in French, but its tangy flavor profile is due to the fermentation process involved in its production.
- The basic ingredients used to make crème fraîche are heavy cream or whipping cream and a bacterial culture, typically Lactobacillus acidophilus or Bifidobacterium bifidum, which is added to the cream to initiate fermentation.
- This process breaks down some of the lactose in the cream, producing lactic acid and giving crème fraîche its characteristic sour taste and thick texture.
Key Characteristics
- Thickness: Crème fraîche has a smooth and creamy consistency that’s thicker than regular sour cream.
- Taste: It has a mild, slightly sweet flavor with a tangy kick due to the lactic acid produced during fermentation.
- Shelf life: When stored properly in the refrigerator, crème fraîche can last for several weeks without spoiling.
Chef John’s Crème Fraîche Recipe
Chef John recommends using a mixture of heavy cream and buttermilk to make his version of crème fraîche. The addition of buttermilk increases the acidity level, which helps to speed up the fermentation process.
To start making Chef John’s crème fraîche recipe, you will need:
- 1 cup heavy cream
- 2 tablespoons buttermilk
- Optional: Salt and any desired flavorings (e.g., herbs, spices, or citrus zest)
Combine the heavy cream and buttermilk in a bowl, then cover it with plastic wrap or a lid and let it sit at room temperature for several hours or overnight to allow fermentation to occur.
The resulting crème fraîche can be stored in an airtight container in the refrigerator. Chef John suggests giving it a good stir before using and adjusting its flavor by adding a pinch of salt or other seasonings if desired.
Crème fraîche is a type of dairy product that originated in Europe, specifically in France and Germany. It’s a mixture of heavy cream and bacterial cultures, which gives it a thick and creamy texture.
Crème fraîche is a type of dairy product that has been enjoyed by people for centuries, particularly in France and Germany where it originated. At its core, crème fraîche is a mixture of heavy cream and bacterial cultures, which gives it a unique texture and flavor.
The addition of bacterial cultures to the heavy cream is what sets crème fraîche apart from other dairy products like sour cream or buttermilk. These bacteria, typically Streptococcus thermophilus and Lactobacillus bulgaricus, ferment the lactose in the cream, producing lactic acid and giving crème fraîche its characteristic tangy taste.
The fermentation process also contributes to the thick and creamy texture of crème fraîche. As the bacteria feed on the sugars in the cream, they produce compounds that help to thicken the mixture. This makes crème fraîche an ideal ingredient for sauces, dressings, and dips, as it adds a rich and velvety texture without being too heavy or overpowering.
One of the benefits of using crème fraîche in cooking is its ability to add depth and complexity to dishes without overpowering them. It’s often used as a topping for soups, salads, and baked potatoes, but it can also be used as an ingredient in sauces, marinades, and dressings.
When shopping for crème fraîche, it’s essential to choose a high-quality product that is rich and creamy. Look for a product that has not been ultra-pasteurized or homogenized, as these processes can damage the natural bacteria and alter the texture of the cream.
In Chef John’s Crème Fraîche Recipe, he uses crème fraîche as a topping for roasted vegetables. The acidity and richness of the crème fraîche balance perfectly with the sweetness of the roasted vegetables, making it a delicious and satisfying side dish.

- Cream: Heavy cream with a fat content of at least 36% (preferably around 40%). You can use either whole, low-fat, or nonfat milk, but keep in mind that the flavor and texture may vary slightly.
- Salt: Unrefined sea salt or kosher salt for added depth of flavor. This will help to balance out the natural sweetness of the cream and give it a richer taste.
- Cream stabilizer (optional): Lactic acid, calcium chloride, or other stabilizers may be used to enhance the stability and shelf life of your crème fraîche. However, for this recipe, we will focus on traditional methods without additives.
In terms of equipment, you will need:
- Thermal mixing tank: A stainless steel or glass container with a thermometer and stirrer for heating and cooling the mixture.
- Heat exchanger (optional): For precise temperature control and efficient heat transfer. This is not essential but highly recommended for optimal results.
- Cooling system: A cold water bath or an ice bath to slow down the cooling process and prevent excessive growth of unwanted bacteria.
- Pipettes or measuring cups: Accurate measuring equipment to ensure precise addition of culture, salt, and other ingredients.
- Cultivation vessel (optional): For incubating the crème fraîche at a controlled temperature (around 72°F to 75°F). A food-grade plastic or glass container with a lid will suffice.
With these main ingredients and equipment in hand, you are now ready to embark on the art of creating your own perfect crème fraîche recipe under the guidance of Chef John’s expertise.
To make Chef John’s crème fraîche recipe, you’ll need 1 cup of heavy cream, 1 tablespoon of buttermilk or plain yogurt containing live cultures, and a pinch of salt. You’ll also need a mediumsized bowl, a whisk, and a glass jar with a lid.
To make Chef John’s crème fraîche recipe, you’ll need a few key ingredients to get started. Here are the necessary items:
- 1 cup of heavy cream: This is the base ingredient for our crème fraîche and will provide the rich, creamy texture.
- 1 tablespoon of buttermilk or plain yogurt with live cultures: The addition of buttermilk or yogurt with live cultures is crucial in creating the tangy flavor and thickening agent that characterizes crème fraîche.
- A pinch of salt: A small amount of salt will enhance the flavors and help bring out the other ingredients. Use a light hand when adding salt, as it can quickly become overpowering.
As for equipment, you’ll need:
- A medium-sized bowl: This is where we’ll combine our cream and buttermilk or yogurt, and then whisk the mixture until it’s smooth and even.
- A whisk: We’ll use a whisk to blend the ingredients together until they’re well combined. A wire whisk or a balloon whisk will work perfectly for this task.
- A glass jar with a lid: Once we’ve transferred the crème fraîche mixture to a glass jar, we’ll cover it with a lid and let it chill in the refrigerator until it’s thickened. Look for a jar that’s large enough to hold at least 1 cup of liquid.
Now that you have all the ingredients and equipment necessary, it’s time to start making your crème fraîche! Simply combine the heavy cream and buttermilk or yogurt in the medium-sized bowl. Add a pinch of salt and whisk until well combined. Be careful not to over-whisk – this can lead to a grainy texture.
Preparing the Perfect Crème Fraîche
Step-by-Step Instructions
To prepare the perfect crème fraîche, you’ll need to follow a simple yet crucial process that involves allowing time for fermentation.
Start by combining 1 cup (240 ml) of heavy cream with 2 tablespoons of buttermilk in a clean glass or ceramic container. Make sure the container is non-reactive and has a wide mouth to allow for easy mixing and access during the fermentation process.
Cover the container with plastic wrap or a lid, and let it sit at room temperature (around 70°F to 75°F) for 8 to 24 hours. The longer it sits, the thicker and more sour the crème fraîche will become, so you can adjust the fermentation time based on your personal taste preferences.
After the desired fermentation period has passed, give the mixture a gentle stir to redistribute the curds. You’ll notice that the mixture has started to thicken and separate into a solid mass of curds and a liquid whey.
Line a fine-mesh strainer with cheesecloth or a clean, thin kitchen towel, and place it over a bowl or another container. Carefully pour the crème fraîche mixture into the lined strainer, allowing the excess whey to drain off into the bowl below.
Gather up the edges of the cheesecloth or towel and give the curds a gentle squeeze to remove any remaining liquid. You can discard the whey or save it for another use in cooking or baking.
Transfer the crème fraîche to an airtight container, such as a glass jar with a tight-fitting lid, and store it in the refrigerator to chill before serving.
Note: Once you’ve made your own crème fraîche using this recipe, you can use it as a base for other recipes or flavor it with various ingredients like herbs, spices, or citrus zest to create unique variations.
Mix the heavy cream, buttermilk or yogurt, and salt in the bowl until well combined. Cover the bowl with plastic wrap and let it sit at room temperature (about 70°F to 75°F) for 8 to 12 hours or overnight. After the incubation period, transfer the mixture to a glass jar with a lid and refrigerate it. Let it chill for at least 2 hours before serving.
The key to preparing the perfect crème fraîche lies in its incubation period, during which it undergoes a slow and gentle fermentation process that allows its flavors and textures to develop.
Mixing heavy cream, buttermilk or yogurt, and salt together is just the beginning. The mixture should be well combined so that no lumps form, ensuring an even development of flavor throughout the incubation period.
Next, cover the bowl with plastic wrap to prevent contamination and keep dust particles out, then let it sit at room temperature (about 70°F to 75°F) for 8 to 12 hours or overnight. This will allow the mixture to ferment slowly and evenly, resulting in a rich and tangy crème fraîche.
After the incubation period has passed, transfer the mixture to a glass jar with a lid to allow it to chill and thicken further in the refrigerator.
Let it chill for at least 2 hours before serving to allow its flavors to settle and intensify. This will give you a rich and creamy crème fraîche that’s perfect as a topping, a base for sauces, or even used in baked goods and desserts.
Note: The United States Department of Agriculture (USDA) recommends that crème fraîche be stored in the refrigerator at a temperature of 40°F or below.
To prepare the perfect crème fraîche, you will need the following ingredients:
