Ingredients:
- 2 cups Heavy Whipping Cream (at least 36% milk fat)
- 1/2 tsp Fine Sea Salt (Optional)
- 1/4 cup Ice Water (For washing)
Instructions:
- Ensure the heavy cream is very cold (straight from the fridge).
- Place the cold cream into a stand mixer fitted with a whisk attachment. Begin mixing on medium speed, gradually increasing to high. Whip until very stiff peaks form.
- Continue beating past the stiff peak stage. The mixture will deflate and suddenly separate into yellow butterfat clumps and a watery liquid (buttermilk). Stop immediately once separation occurs.
- Pour the contents through a fine-mesh sieve set over a large bowl to drain and reserve the fresh buttermilk.
- Transfer the butter solids to a clean bowl. Pour 1/4 cup of ice water over the solids. Knead and press the butter gently with a spatula until the water turns cloudy.
- Drain the cloudy water. Repeat the washing process (Step 5) with fresh ice water until the water being squeezed out runs completely clear. This is crucial for shelf life.
- If making salted butter, press the clear water out, then gently mix in the salt until evenly distributed.
- Shape the finished butter into a log using parchment paper or plastic wrap. Chill for at least 1 hour to allow it to firm up before serving.
