Sweet potatoes come in all shapes and sizes and, being Cuban, the one I grew up with is the one that you will most commonly find there: the boniato.
Boniato is know as the Cuban sweet potato with its dry, white flesh and skin that ranges in color from pink to purple. Although also commonly referred to as a Florida yam, it is indeed a sweet potato that is often used in Cuban cuisine. I love them because they are an excellent source of Vitamin C and fiber. But, I have to admit, I never tried making mashed potatoes with boniato until this past Christmas.
