From America's Test Kitchen TV Show -- Boiling sweet potatoes in lots of liquid -- as you would regular potatoes -- is not a good idea. Sweet potatoes will soak up too much water, and the resulting mash will be a soggy mess. Better to cook them in a small amount of liquid. America's Test Kitchen found that a combination of butter and cream yielded the creamiest potatoes. Just 2 Tbls. of heavy cream (plus a little butter), along with the water released from the sweet potatoes as they cook, is enough to steam them into tenderness.
