What each ingredient does
- Salt butter
- Supplies fat and richness, and gives the finished butter its flavour and texture.
- New milk
- Provides the cream whose fat clumps together during churning to form the butter.
The step that matters
Churn the mixture together for about an hour. Continuous agitation ruptures the fat globule membranes so the fat clumps into butter and separates from the liquid buttermilk. Stopping too early leaves the butter soft and unformed.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
