Over the centuries, yuletide revelers have enjoyed far different culinary fare than we do today. Here are seven Christmas dishes of yesteryear that are sure to confuse—or tantalize—your taste buds.

1. PEACOCK

 
During the Medieval ages, some wealthy Europeans dined on peacock at Christmas dinner. The colorful, plumed bird was often baked into a pie, or roasted with its head and tail still intact. Adding to the flamboyant display, the peacock’s feathers were reattached (or the skinned bird was placed back inside its intact skin), and its tail feathers were fully fanned out.

Peacocks likely looked impressive on a banquet table, but the meat reportedly tasted terrible. “It was tough and coarse, and was criticized by physicians for being difficult to digest and for generating bad humors,” author Melitta Weiss Adamson writes in her book Food in Medieval Times. “To make the meat more easily digestible, it was recommended to hang the slaughtered bird overnight by its neck and weigh down the legs with stones.”

In addition to peacock, swans and geese were also on the Christmas menu. But by the 1520s, another roast delicacy—turkey—had been introduced to Great Britain. Explorer William Strickland is credited with bringing the turkey from the New World to England, and King Henry VIII was reportedly one of the first people to enjoy the new bird for Christmas dinner. Edward VII is said to have made the meal trendy.

2. BOAR'S HEAD

In Medieval and Tudor England, wealthy parties celebrated Christmas by feasting on boar's head. The boar's head "formed the centrepiece of the Christmas Day meal," writes Alison Sim, author of Food and Feast in Tudor England (as quoted by the Food Timeline). "It was garnished with rosemary and bay and evidently was presented to the diners with some style, as told by the many boar's head carols which still exist."

One English Christmas carol, dating back to the 15th century, is actually called the "Boar's Head Carol." Its lyrics include lines like "The boar's head, as I understand/Is the rarest dish in all this land/Which thus bedecked with a gay garland/Let us servire cantico (serve with a song)."

3. OYSTER STEW

Today, oysters are a delicacy, but for early Americans who settled along the East Coast, they were a plentiful and nutritious food source. People enjoyed them in stuffing, roasts, and chowder—and 19th-century Irish-American immigrants used them to make a traditional Christmas Eve stew.

Most of these Irish transplants were Catholic, and their religious traditions required them to skip the meat on Christmas Eve. Instead, they enjoyed a soup made from dried ling cod—a common fish back in the Old Country—milk, butter, and pepper. But since Irish Americans couldn’t find dried ling cod in America, they substituted it with fresh, canned, pickled, or dried oysters.

4. MINCEMEAT PIES

Historians trace mincemeat pie (also called mince pie) back to the 11th century, when Crusaders returned from faraway lands with spices. These spices worked as a preservative, so they were baked into pies containing finely chopped meat, dried fruits, and other ingredients.

Mincemeat pies eventually became associated with Christmas. Bakers added three spices to their pies—cinnamon, cloves, and nutmeg—to represent the three gifts the Magi gave the baby Jesus. The pies were also baked into the shape of Jesus’s manger, and a model of the Christ Child was placed on top. People believed that eating a mincemeat pie on each of the 12 Days of Christmas (December 25 to January 6) would bring them good luck.

Over the centuries, the pies grew smaller and rounder, and their filling became less meat heavy, containing ingredients including suet, spices, and dried and brandied fruit. Today, some people still eat mincemeat pie in England—and on December 15 some British scientists fired a meat pie into space—but it’s not commonly seen on Christmas dinner tables in the U.S.

5. SUGARPLUMS

As a child, you might have been inspired by one of ballet's most famous movements—The Nutcracker's “Dance Of The Sugarplum Fairy"—to wonder what a "sugarplum" actually is. The answer? A hard candy.

Between the 17th and 19th centuries, the term sugarplum was interchangeable with the words dragee or comfit. All referred to a hard, sugary layered candy. Often, the candy contained caraway, cardamom, fennel, ginger, cinnamon, walnut, aniseed, and almond cores. It took time, skill, and special equipment to make these sweets, so they were originally quite expensive and eaten only by wealthy people. Later, innovations in manufacturing made both sugarplums and other candies cheaper, and available for consumption by the masses.

In addition to getting a shout-out in The Nutcracker, sugarplums are also famously mentioned in Clement Clark Moore's anonymously published 1823 poem "A Visit from St. Nicholas," better known as "Twas the Night Before Christmas" after its first line. But today, you're far less likely to see the candies mentioned in a ballet or poem; according to the Oxford English Dictionary, sugarplum is now obsolete.

6. POSSET

Long ago, the English enjoyed a predecessor to eggnog called posset, a kind of "wine custard" made from hot milk curdled with hot ale, wine, or sherry, and mixed with sugar and spices. The drink remained common from the Middle Ages until the early 19th century; over time, it disappeared from the culinary landscape.

Throughout the centuries, winter revelers enjoyed variations on the recipe, and eggs were eventually added to the mix. But since milk, eggs, and liquors like sherry and Madeira wine were either expensive or hard to come by, the drink’s popularity dwindled among the masses. Meanwhile, in America, early settlers created their own version of posset, which we today know as eggnog.

In the video above, you can watch Jonathan Townsend, host of YouTube living history channel Jas. Townsend and Son, cook his own version of posset, as adapted from an 18th-century cookbook. His posset has breadcrumbs.

7. ANIMAL CRACKERS

Ever wondered why boxes of Barnum's Animal Crackers have a string attached to them? In 1902, the National Biscuit Company (today known as Nabisco) introduced the circus-themed boxes filled with animal-shaped cookies as a seasonal promotion. Since people often adorned their Christmas trees with candy and/or treats, Barnum’s festive containers were hung on branches as decorations.
