How to prepare mashed potatoes

Paul Turner of The Slice blog posts:

“In reference to the child who suggested smashed potatoes to be served with the Thanksgiving turkey (Tuesday’s Slice), he could be one of my family members,” wrote Catherine Short. “We have a recipe (from New Zealand) for smashed potatoes, which consists of partially boiled potatoes, in their skins, smashed (gently) and then baked with olive oil, butter, lemon juice and herbs. Scrumptious.”

Question: Do you have a way of preparing mashed potatoes that differs from the norm?
