1. Starbucks Sweet Potato Frappuccino
Sweet potatoes for many Americans remind Thanksgiving. But for across East Asia, they use sweet potatoes as a flavor for many (even too much) varieties of foods. Starbucks launched in 2019 in Japan a seasonal drink that literally contain sweet potatoes in it and that is named Sweet Potato Gold Frappuccino.
This drink contains small touches of candied sweet potato along with a honey and sweet potato sauce. People that tasted this interesting drink report the flavor of the drink is quite interesting and they could feel the the sweet potatoes taste with strong taste of espresso.
