You can use olive oil to roast these potatoes but they would just be more evil if you use duck fat. Sometimes, potatoes call out to be more evil.

Ingredients:
1 bag of small white potatoes, rinsed thoroughly, halved
duck fat
1 bunch of flat-leaf parsley, roughly chopped
salt, pepper

1. Put potatoes on roasting pan. Drizzle with duck fat. Sprinkle with salt and pepper and parsley. Bake for about 30 minutes.
