What each ingredient does

Rennet
An enzyme that clots the milk protein into a firm curd.
Milk
Supplies the casein protein that sets into the curd, leaving the watery whey behind.

The step that matters

Separate the whey by gentle pressure. Pressing too hard forces fine curd particles through and squeezes out the solids, so the whey comes out cloudy and the curd loses its softness. Gentle pressure lets the liquid drain slowly while the curd stays intact.
