The sweet tang of Vietnamese yogurt brightens the flavor of this drink from Phin in Seattle. Owner Bao Nguyen makes his own yogurt for the drink at the café but says you can easily find Vietnamese yogurt at Vietnamese supermarkets and delis. For the coffee, he recommends Phin Coffee Club out of Dallas. “A departure from the light and medium roast of modern specialty Vietnamese coffees, we appreciate Phin Coffee Club’s old-school, super-dark, and smoky flavors that remind me of folks roasting coffee in steel drums in Vietnam.”
