What each ingredient does

Buttermilk
Its acidity causes the milk proteins to curdle when heated, separating the whey.
Sweet milk
Provides the protein and liquid that curdle into solids while the whey separates out.

The step that matters

Gently stir the buttermilk around the edges of the pan. Stirring gently keeps the curds from scorching or sticking to the hot pan edges, and avoids breaking up the forming curds too finely, which would make the whey cloudy and harder to strain.
