Made with both sweet and white potatoes,this dish is a blend of color,taste,and texture. It's creamy,but not too heavy,and sweeter and less starchy than it would be with all white potatoes.
I'm an ole gal ; ) ~~ so I use a food processor to slice my potatoes to be thinly sliced. And if I use the Red potato in place of the White. I wash em up and leave skins on and then slice thinly.
