Popover

A popover is a light roll made from an egg batter similar to that of Yorkshire pudding, typically baked in muffin tins or dedicated popover pans, which have straight-walled sides rather than angled. Popovers may be served either as a sweet, topped with fruit and whipped cream; or, butter and jam for breakfast; or, with afternoon tea; or, with meats at lunch and dinner. The name "popover" comes from the fact that the batter swells or "pops" over the top of the tin while baking. Popovers are also known as Laplanders.
