Vietnamese-style iced coffee commonly combines a concentrated coffee preparation with sweetened condensed milk and ice. A phin places a small brewing chamber over the serving cup, allowing water to pass through the coffee and its perforated filtering parts. Different phin designs use different inserts, so follow the particular device rather than assuming every model has a screw adjustment.
Place a measured quantity of condensed milk in the cup, prepare the phin with a suitable coffee dose and add the water as directed. Once brewing is complete, stir the coffee and milk thoroughly before deciding how much ice to add. Sweetened condensed milk is not the same ingredient as unsweetened evaporated milk, and substituting one changes the recipe substantially.
The source collects several variations, so its different quantities should not be combined into a new formula accidentally. Select one complete version and keep its serving size clear. Ice, coffee strength and milk quantity all affect the balance. A repeatable glass comes from controlling those components, not merely waiting for the slowest possible drip.
