What each ingredient does

Fresh ground coffee
Provides the main flavour and aroma of the brew.
Isinglass chips
Acts as a fining agent that gathers fine particles so the coffee settles clearer.

The step that matters

Returning the poured-out coffee to the pot. Pouring the coffee back and forth mixes the grounds through the liquid and helps extract flavour evenly, while the isinglass later needs the brew to be settled rather than churned.
