Prep: 10 min | Cook: 48 hrs | Total: 48 hrs 25 min

Cost: $2.30 total, $0.57 per serving

Ingredients

  • 2 cups Heavy Whipping Cream (full‑fat (≈36% milkfat), cold)
  • 3 tablespoons Cultured Buttermilk (live‑culture buttermilk, not powdered)

Instructions

  1. Sterilize the Jar

    Bring a pot of water to a boil, submerge the clean jar (without lid) for about five minutes, then remove with tongs and let it air‑dry.

    Time: PT5M

  2. Combine Cream and Buttermilk

    Pour the 2 cups of heavy whipping cream into the sterilized jar, add 3 tablespoons of cultured buttermilk, and stir gently with a clean spoon until evenly mixed.

    Time: PT5M

  3. Cover with a Breathable Filter

    Place a coffee filter over the jar opening and secure it with a rubber band so air can flow but dust cannot enter.

    Time: PT1M

  4. Incubate the Mixture

    Set the jar in a warm spot (about 70°F/21°C) such as an oven with the light on, and let it sit undisturbed for 24 hours.

    Time: PT24H

    Temperature: 70°F

  5. Check Thickness

    After 24 hours, the cream should have thickened to a spoon‑coating consistency. If it is still runny, continue incubating another 6–12 hours.

    Time: PT2M

  6. Refrigerate to Finish

    Seal the jar with its lid and place it in the refrigerator for another 24 hours. The cold will firm the texture and develop a deeper tang.

    Time: PT24H

    Temperature: 4°C

  7. Serve or Store

    Stir the finished crème fraîche, then use it as a topping, dip, or cooking ingredient. Keep refrigerated and consume within 2 weeks.

    Time: PT2M

Frequently Asked Questions

Everything you need to know about this recipe

Q

What is the cultural significance and history of crème fraîche in French cuisine?

A

Crème fraîche originated in the French countryside as a way to preserve cream before refrigeration. Its slightly tangy, nutty flavor made it a versatile ingredient in sauces, soups, and desserts, and it remains a staple in classic French cooking.

cultural
Q

What are the traditional regional variations of crème fraîche in French cuisine?

A

In the Alpine regions, crème fraîche is often made with raw milk cream and left to ferment longer, resulting in a thicker, more pronounced tang. In Normandy, a lighter version is used for seafood dishes, while in Provence it may be flavored with herbs for serving with grilled vegetables.

cultural
Q

How is authentic crème fraîche traditionally served in France?

A

Authentic crème fraîche is served chilled as a garnish for fruit, incorporated into sauces like sauce béarnaise, or dolloped onto soups such as potato leek. It is also used as a base for desserts like clafoutis and as a topping for fresh berries.

cultural
Q

What occasions or celebrations is crème fraîche traditionally associated with in French culture?

A

Crème fraîche appears on holiday tables during Christmas and New Year’s feasts, especially in creamy gratins and baked dishes. It is also a common component of celebratory brunch spreads, paired with fresh pastries and fruit.

cultural
Q

How does crème fraîche fit into the broader French cuisine tradition?

A

Crème fraîche exemplifies the French emphasis on dairy richness and balanced acidity. It bridges the gap between heavy cream and sour cream, allowing chefs to add body and tang without curdling, which is essential in many classic French sauces and soups.

cultural
Q

What are the authentic traditional ingredients for crème fraîche versus acceptable substitutes?

A

Traditional crème fraîche uses only heavy cream and a live‑culture starter such as cultured buttermilk. Acceptable substitutes include a mixture of heavy cream with a tablespoon of plain yogurt or kefir, though the flavor and texture may differ slightly.

cultural
Q

What other French dishes pair well with homemade crème fraîche?

A

Homemade crème fraîche pairs beautifully with beef stroganoff, chicken à la king, mushroom sauces, baked potatoes, and fruit tarts. It also works as a luxurious topping for poached pears or a base for herb‑infused dips.

cultural
Q

What makes homemade crème fraîche special or unique compared to store‑bought sour cream?

A

Homemade crème fraîche has a higher fat content, giving it a silkier mouthfeel and a deeper, nutty tang. Unlike sour cream, it can be heated without curdling, making it ideal for sauces and soups that require simmering.

cultural
Q

What are the most common mistakes to avoid when making crème fraîche at home?

A

Common mistakes include using pasteurized buttermilk without live cultures, incubating at too low a temperature, or contaminating the jar with unsterilized equipment. Also, overheating the cream before adding the starter can kill the beneficial bacteria.

technical
Q

Why does this crème fraîche recipe use no heating of the cream before adding the starter?

A

Chef John’s method relies on the ambient warmth of the kitchen (around 70°F) to activate the cultures gently, preserving the delicate flavor of the cream. Heating can denature some of the proteins and alter the final texture, so the no‑heat approach yields a smoother product.

technical
Q

Can I make crème fraîche ahead of time and how should I store it?

A

Yes, you can make it up to two weeks in advance. Keep the sealed jar in the refrigerator at 4°C; the flavor will continue to develop, and the texture will stay thick as long as it remains chilled.

technical
Q

What does the YouTube channel Food Wishes specialize in?

A
