What each ingredient does
- Ground coffee
- Supplies the flavor compounds that dissolve into the hot water to make the drink.
- Egg
- As its proteins cook in the hot liquid, they can help bind the fine grounds so they settle.
The step that matters
Let it boil for a few minutes. Boiling extracts flavor from the grounds, and holding the coffee at a boil for too long pulls out more bitter compounds, so timing matters for taste.
