Le Beurre Tendre is a premium French cultured butter made with cream, milk fat, and lactic ferments - already clean with no seed oils or artificial ingredients. DIY is worthwhile for organic sourcing, cost savings, and controlling the fermentation process for optimal flavor and digestibility.

Why This Recipe is Seed Oil Free
Commercial Le Beurre Tendre from Elle & Vire often contains inflammatory seed oils like canola, soybean, or sunflower oil. This homemade version replaces them with healthier fats like butter, ghee, coconut oil, or avocado oil — giving you the same great taste without the processed oils.
Ingredients
Organic Heavy Cream (36-40% fat)
946ml (1 quart = about 4 cups) · Organic Valley Heavy Whipping Cream or Kalona SuperNatural
Primary fat source that will be churned into butter - provides the rich, creamy base with natural milk fat
Cultured Buttermilk (live cultures)
60ml (4 tablespoons) · Kate's Real Buttermilk or Kalona SuperNatural Cultured Buttermilk
Provides lactic acid bacteria for fermentation, creating the tangy flavor and tender texture characteristic of cultured butter
Sea Salt (fine)
2-4g (1/2 to 1 teaspoon) · Redmond Real Salt Fine or Celtic Grey Sea Salt
Enhances flavor and acts as a natural preservative - optional but recommended for taste balance
Instructions
Step 1. Combine 946ml (4 cups) organic heavy cream with 60ml (4 tablespoons) cultured buttermilk in a clean glass jar or bowl. Whisk gently for 30 seconds to distribute the cultures evenly throughout the cream. The live bacteria need to be evenly dispersed to create uniform fermentation.
Step 2. Cover the mixture with a clean kitchen towel and let it culture at room temperature (68-72°F) for 12-18 hours. The cream will thicken slightly and develop a tangy aroma - this is the lactic acid bacteria converting lactose into lactic acid, which tenderizes the final butter. In cooler weather, this may take up to 24 hours.
Step 3. Chill the cultured cream in the refrigerator for at least 2 hours until it reaches 60-65°F. This temperature is crucial - too warm and the butter won't form properly, too cold and it will take much longer to churn. The cream should feel cool but not ice-cold to the touch.
Step 4. Pour the chilled cultured cream into a food processor, stand mixer with whisk attachment, or large mason jar if making by hand. Begin churning at medium speed (or shake vigorously if using jar method). After 3-5 minutes, the cream will become thick whipped cream, then suddenly 'break' and separate into golden butter curds and white buttermilk.
Step 5. Strain the mixture through a fine-mesh sieve, pressing the butter curds gently to extract buttermilk. Reserve the buttermilk for baking - it's cultured and delicious. Rinse the butter curds under cold running water while gently kneading with clean hands until the water runs clear, about 2-3 minutes. This removes excess buttermilk and prevents rancidity.
Step 6. Transfer the washed butter to a clean bowl and work in 2-4g (1/2 to 1 teaspoon) of fine sea salt using a wooden spoon or paddle. Work just until evenly distributed - overworking will make the butter tough. Taste and adjust salt if needed. The butter should have a clean, slightly tangy flavor with no grittiness.
Step 7. Shape the butter into a log using parchment paper or press into a butter mold. For the signature 'tender' texture of the original, store at 60-65°F (slightly warmer than typical refrigeration) or let soften at room temperature for 15-20 minutes before serving. Use within 1-2 weeks when stored properly in the refrigerator.
Storage
Store covered in refrigerator for up to 2 weeks, or freeze for up to 6 months. For optimal spreading consistency, remove from fridge 15-20 minutes before use. Keep away from strong odors as butter absorbs flavors easily.

Significant savings despite premium organic ingredients. Initial investment in buttermilk and salt covers many batches. Fresh homemade cultured butter tastes superior and contains beneficial live cultures.
