the.com/christmas pudding

means A dense, boozy, dried-fruit-packed British steamed pudding, traditionally served flaming at the end of Christmas dinner.

from Its ancestor is medieval 'frumenty,' a savory boiled porridge of meat, grains, and dried fruit. By the 1600s this had evolved into 'plum pudding' — 'plum' then meaning dried fruit generally, especially raisins, not the fruit itself — bound with suet and boiled in a cloth bag. The custom of dousing it in brandy and setting it alight is thought to date to the 1800s, and the stirring rituals (a coin baked inside, everyone taking a turn stirring east to west for the Magi) became fixed Victorian traditions, cementing the pudding as Christmas's most combustible course.
