What each ingredient does

Fresh-ground coffee
Provides the main flavour and aroma that the hot water extracts.
Isinglass
Fining agent that helps clear the coffee by binding fine particles so they settle.

The step that matters

Pouring out a cupful and returning it to the pot. Repeatedly drawing off liquid and pouring it back circulates the brew and mixes the grounds through it, which helps the coffee extract evenly before fining.
