In a glass or coffee mug, add sweetened condensed milk. Place coffee grounds in an 8 ounce phin, level and compact (but not too hard.) Put phin on top of coffee mug.

Bring water just to a boil. Add a small amount of hot water gently to the phin and wait 30 seconds for grounds to absorb the water. Then slowly add the rest of the hot water. If done correctly, a strong coffee will brew over the course of the next 3 to 5 minutes.

Once fully brewed, stir well to combine milk and coffee. In a separate taller glass add ice and pour coffee over. Or enjoy your coffee hot!
