The changing Christmas entrée and how Charles Dickens helped standardize the turkey.
Boar’s Head
Before a goose at Christmas, and long before turkey, boar was the star of the English Christmas feast. At the table of the rich in Medieval England a cooked boar’s head was the main attraction. It was so special that it had its own Christmas carol (the Boar’s Head Carol) which would be sung as it was paraded into the hall.
While recipes varied, any way you cooked it the boar’s head was labor intensive. The head would be removed from the body, the skin would be carefully separated from the skull, cured meats and other ingredients would be stuff into the skin, it would be sewn back together, the whole head would be covered in muslin cloth, boiled, garnished, then dressed up with an apple in its mouth and perhaps some black ash to simulate fur.
An added bonus at the table was roasted “gilded peacock”. Since the wow factor of a peacock is its showy feathers, the peacock’s head & skin was removed, the body was roasted, then the bird was put back together to be both edible and a showpiece. Also like the boar’s head it was only found on the tables of the wealthiest elite. That said it was mostly for show since apparently it didn’t taste particularly good.
As for the common people, depending on their finances they might have salted pork of some kind but a reliable alternative was pottage. Pottage was anything cooked in a pot. Special Christmas recipes might add certain spices as a seasonal treat. The most unfortunate of society could expect some of the feast leftovers, trenchers, and other scraps given as donations at the gates of clergy and the upper class. That said after waves of bubonic plague in the mid 14th century, which killed more people than animals, there was more meat available in general for all levels of society.
Goose
The goose became the Christmas entrée of choice in the 16th century when (supposedly) Queen Elizabeth I ordered others to eat roast goose for Christmas because that’s what she was eating when she heard the news of the English victory over the Spanish Armada in 1588.
As a main dish goose was a smart choice since it was something almost everyone could enjoy. Geese can be farmed (unlike wild boar), they don’t lay as many eggs as chickens so there is less reason to keep them around, they don’t provide milk like cows, they are larger than chickens so they can feed more people, and they take up less room than pigs. Geese also make exceptional guard animals (during the time you are raising them … before you cook them).
In the 19th century Queen Victoria preferred the traditional boar’s head for Christmas dinner but for most people goose was the standard. Cooking a goose however could be challenging depending on the kitchen. Too close to the fire a goose burns on the outside while being uncooked on the inside. The fat from the bird can drip into the fire causing bursts of flames. Also the size of the bird was difficult to accommodate if other things were being cooked. All of which led many Victorian Londoners to take their geese to their local bakeries who had seasonal side businesses of cooking people’s geese for them in their large bakery ovens (something Scrooge sees when he is traveling with the Ghost of Christmas Present in A Christmas Carol).
Turkey
Turkey comes from North America and some of the first turkeys to reach England were supposedly imported by William Strickland in 1526. He later had the turkey as part of his family crest. Initially turkeys were only for the wealthy since there were so few birds available. They were a status symbol and an exotic delicacy like how peacock had been, but unlike peacock a turkey tasted good.
By the Victorian era turkey was still a luxury but was no longer solely for the ultra rich. It was becoming more accessible to more people. Charles Dickens was a fan of turkey, so much so that the Cratchit family are gifted a prize winning turkey at the end of 1843’s A Christmas Carol.
The success of A Christmas Carol was so great that it not only reinvigorated the celebration of Christmas but it also popularized the idea of having a turkey for Christmas dinner instead of a goose. By the early 20th century advancements in farming both brought the price of turkeys down, and fattened the birds up, so as to make them Christmas feasts for everyone.
