Place dripper with wet paper filter on top of the pitcher. Add coffee grounds into the paper filter.
Pour just enough hot water from your kettle in a circular motion to saturate the grounds. Wait for about 1 minute to let the grounds bloom.
Slowly and evenly pour the rest of the water from your kettle over the grounds in a circular motion, keeping the water level fairly constant in the dripper as the coffee drips down. Total brew time takes about 8 minutes.
Mix the coffee and sweetened condensed milk together. Pour over ice and serve immediately.
