From America's Test Kitchen Season 8: Holiday Beef Tenderloin Dinner
Sometimes we want a luxurious mash, one that is silky smooth and loaded with cream and butter. But there’s a fine line between creamy and gluey. We wanted lush, creamy mashed potatoes, with so much richness and flavor they can stand on their own—no gravy necessary.
For a creamier, substantial mash, we found that Yukon Golds were perfect—creamier than russets but not as heavy as red potatoes. Slicing the peeled potatoes into rounds and then rinsing away the surface starch before boiling helped intensify their creamy texture without making them gluey. Setting the boiled and drained potatoes in their pot over a low flame helped further evaporate any excess moisture. Using 1 1/2 sticks of butter and 1 1/2 cups of heavy cream gives these potatoes luxurious flavor and richness without making the mash too thin. We found that melting the butter and warming the cream before adding them to the potatoes ensured that the finished dish arrived at the table piping hot.
