Cultured butter at home
You'll need
- 1 quart raw heavy cream
- ⅛ tsp mesophilic culture (like MM 100), or 2 tbsp cultured buttermilk
- A big bowl of ice water
- Salt, if you like
Method
- Pour the cream into a clean glass or stainless steel bowl and warm it gently to about 77°F.
- Stir in the culture. Cover it and keep it near 77°F for about 24 hours, until it thickens and smells pleasantly tangy.
- Set the bowl in ice water and chill for 12 to 24 hours, until it’s cold all the way through.
- Beat the cold cream in a stand mixer on medium. It will go past whipped cream and suddenly break into yellow butter and thin buttermilk.
- Pour off the buttermilk and save it for baking.
- Press the butter under very cold water, changing the water until it runs clear. Salt it if you like, pack it into a jar and chill.
Tip: In a hurry? Skip the culturing and just chill the cream well. You’ll get sweet-cream butter instead.
