The tricks to achieving very creamy mashed potatoes are to not overcook them and to whip them just until smooth (if you overwhip, they’ll get gluey). Serve some of the butter on the side, so guests can determine their level of richness.
This Spanish classic is typically a thin omelet filled with fried potatoes and onions. The recipe is easy to assemble, can be made ahead, warmed when ready, and is great for serving to guests as an appetizer or as part of a meal. It's great on its own, but a little garlicky aïoli is good, too.
