TAKE a quart of potatoes, boil them soft, peel them and mash them with the back of a spoon, and rub them through a sieve, to have them fine and smooth; take half a pound of fresh butter melted, half a pound of fine sugar, beat them well together till they are very smooth, beat six eggs, whites and all, stir them in, and a glass of sack or brandy. You may add half a pound of currants, boil it half an hour, melt butter with a glass of white wine; sweeten with sugar, and pour over it. You may bake it in a dish, with puff-paste all round the dish and at the bottom.
