Joy to the Food

0 Preheat oven to 500 degrees F. Cut potatoes to roughly 1/2 inch thick by 1-2 inch wide pieces. Note: you can peel the potatoes first if you prefer no potato skins, but this is not necessary.
1 Add potatoes to a large pot. Then, fill with cold water until the potatoes are covered with about 1" of water over them. Then, add baking soda and 1 tbsp (3 teaspoons) of salt and stir.
2 Bring the water to a boil. Then, reduce to a simmer on medium heat and cook for 5 minutes. After 5 minutes test that you can insert a fork into one of the potato pieces with little resistance. This is how you know they're done. Once done, drain the potatoes.
3 Mix duck fat (or olive oil) and spices together in a large bowl. Then, add potatoes and mix to fully coat the surface of the potatoes.
4 Place potatoes in a single layer on a baking rack with a large baking tray underneath. Then, bake for 45 minutes. Note: if you don't have a baking rack you can roast the potatoes directly on a sheet pan or large roasting pan. Just be sure to flip them half way through cooking if you do this.
5 Remove from oven, let cool, and enjoy!
