United States: Mashed potatoes are a staple at Thanksgiving, Christmas, and Sunday dinners. Standard side portions range from 200-250g per person. Russet and Yukon Gold potatoes are the most popular choices. Many Americans prefer using heavy cream or half-and-half instead of milk for extra richness.

Maris Piper and King Edward potatoes are preferred varieties. Clotted cream or crème fraîche can replace milk for a luxurious texture.
