2 lbs. potatoes, peeled and halved
2 lbs. parsnips, peeled and halved
Salt
8 tbsp. butter
Cook potatoes and parsnips in large saucepan of lightly salted boiling water for 10 minutes. Drain. Preheat oven to 400 degrees. Place butter in baking dish and put in oven to melt. Scratch surface of potatoes only with a fork to give them crunchy skin when cooked.
When butter is hot and sizzling, add potatoes and parsnips and toss in butter. Roast for about 1 hour, or until crunchy and golden. This dish traditionally served with the Christmas bird in England.
