How to Make a Fried Meat of Turneps
Roast the Turneps in the embers or else boil them whole, then cut or slice them in pieces as thick as half the shaft of a knife, which done, take cheese and cut it in the same form and quantity, but somewhat thinner. Then take Sugar, Pepper, and other spices mingled together, and put them in a pan under the pieces of cheese, as if you would make a crust under the cheese, and on top of them likewise. And over it you shall lay the pieces of Turnips, covering them over with the spices aforesaid, and plenty of good Butter, and so you shall do with the said cheese and Turnips till the pan be full, letting them cook the space of a quarter of an hour, or more, like a Tart, and this would be one of your last Dishes.
