I'm quite curious about the food people ate in the Middle Ages. In The Big Fat Duck Cookbook, Heston Blumenthal mentions his fascination with a bizarre 14th century French cookery book, Le Viander de Taillevent, in which a chicken is plucked alive, basted with soya, wheat-germ and dripping- to simulate roasting, coaxed asleep, and then 'brought back to life' at the table.
In case you're wondering, the rather beautiful illustration is from the Duc de Berry's Book of Hours and depicts the month of January. It probably shows the Twelfth Night banquet, as during the Middle Ages the focus of the Christmas festivities tended to be during the Twelve Days of Christmas, and after the Advent Fast.
I've adapted a 15th century English recipe for "Goose in a Garlic and Grape Sauce" which you could easily make at home. I haven't tried it yet, so I've no idea what it tastes like- it could be foul:
You make a stuffing out of garlic cloves, seedless grapes, chopped parsley and salt, and then stick it up a goose. Roast the bird in an oven set at 350༠C (twenty minutes per pound). When you're happy that the goose is cooked, take it out of the oven, and set aside to cool.
Spoon out the cooked stuffing and blend it in a food processor, adding three hard-boiled egg yolks, and half a cup of cider vinegar. Spoon the finished sauce over the goose.
