Fluffy, luxurious Swedish mashed potatoes whipped with warm farmhouse butter, single cream, sea salt, and freshly grated nutmeg.
Boil potatoes in salted water for 15-20 minutes until completely tender. Drain thoroughly.
Return potatoes to hot pot on low heat for 1 minute, shaking gently to evaporate moisture for lighter mash.
Pass potatoes through a potato ricer into a warm bowl. Add diced butter and stir vigorously until melted.
Gradually whisk in warm cream or milk, grated nutmeg, salt, and white pepper with a balloon whisk until silky and cloud-like.
