Boil water until it reaches 205°F (96°C), the ideal temperature for brewing coffee.
Preheat the coffee phin and cup by pouring hot water through them to maintain optimal brewing temperature and ensure a clean cup.
Discard the water from the cup.
Optional: Add 1-2 tablespoons of sweetened condensed milk to the cup, adjusting the amount based on personal preference for sweetness.
Remove the filter from the phin.
Add 1 heaping tablespoon of Vietnamese coffee grounds to the phin.
Use the filter's press to gently tap down the coffee grounds, creating a flat surface for even extraction.
Place the phin on top of the cup.
Slowly pour hot water into the phin, covering the coffee grounds.
Allow the coffee to drip through the filter into the cup. This may take a few minutes.
Once all the coffee has dripped through, you can either sip it as is or give it a gentle stir to incorporate the condensed milk.
Sit back, relax, and savor the authentic flavors of Vietnamese coffee.
