Samuel Pepys celebrated Christmas 1662 with "a mess of brave plum porridge and a roasted pullet."
It may be the dish referred to in:
Little Jack Horner
Sat in the corner,
Eating his Christmas pie:
He put in his thumb,
And pulled out a plum,
And said, "What a good boy am I!"
Original Receipt in 'The Art of Cookery, Made Plain and Easy' by Hannah Glasse, 1747 (Glasse 1747);To make plum-porridge for Christmas.
TAKE a leg and shin of beef, put them into eight gallons of water, and boil them till they are very tender, and when the broth is strong strain it out; wipe the pot and put in the broth again; then slice six penny loaves thin, cut off the top and bottom, put some of the liquor to it, cover it up and let it stand a quarter of an hour, boil it and strain it, and then put it into your pot. Let it boil a quarter of an hour, then put in five pounds of currants clean washed and picked; let them boil a little, and put in five pounds of raisins of the sun, stoned, and two pounds of prunes, and let them boil till they swell; then put in three quarters of an ounce of mace, half an ounce of cloves, two nutmegs, all of them beat fine, and mix it with a little liquor cold, and put them in a very little while, and take off the pot; then put in three pounds of sugar, a little salt, a quart of sack, a quart of claret, and the juice of two or three lemons. You may thicken with sago instead of bread, if you please; pour them into earthen pans, and keep them for use. You must boil two pounds of prunes in a quart of water till they are tender, and strain them into the pot when it is boiling.
