Wash and peel about six large potatoes ; cut them, lengthwise, in two, and scoop out the centres carefully with a knife or spoon. Fill the cavities with a sausage forcemeat (No. 220), letting it bulge out a little on the top ; butter a baking-pan, arrange the potatoes on it, and cook in a slow oven for half an hour, or until nicely browned, then serve.
