What each ingredient does

Salt butter
Provides the fat base that the added milk is churned with.
New milk
Supplies the fat and liquid that churning separates into butter and buttermilk.
Amotto
Adds a yellow colour to the butter.

The step that matters

Wash the butter thoroughly. Buttermilk left in the butter after churning can turn sour and shorten shelf life. Rinsing it out in water removes the milk solids that would otherwise spoil the butter.
