Thu Pham, the owner and co-founder of Cà Phê Roasters, a specialty Vietnamese coffee company in Philadelphia, recalls how, as a child, she would watch intently as her older sister prepared Vietnamese coffee at their small ranch home in California. She says her sister would pour thick condensed milk right from the can into a glass cup. Then, using a phở spoon, she would scoop coffee grounds into a phin, a Vietnamese coffee filter, and pour piping hot water from a kettle over the grounds. While the dark, syrupy coffee dripped over the velvety condensed milk, her sister would add ice to the glass, and allow Pham to taste just one tiny spoonful. With four siblings to babysit while their parents worked long hours at a sewing factory, Pham says her sister probably relied on that strong dose of caffeine to get her through the day.
