Cook: Bring a large pot of water to a boil. Add some salt, the chopped cauliflower, and potatoes and cook them until soft, about 20-25 minutes. Drain and mash well.
Combine: Add the butter, milk, creme fraiche/sour cream, grated garlic clove, freshly grated nutmeg, salt, and pepper to taste. You can adjust the milk quantity to your liking. Start with 2 or 3 tablespoons and add more for a thinner consistency. Serve hot.
Notes
For a genuine Romanian recipe, use smetana. Otherwise creme fraiche, sour cream or cream cheese are all great.
