Peel and wash five medium-sized Yukon gold potatoes.
Use a mandolin to thinly slice the potatoes.
Pour a quarter cup of duck fat into a large bowl. If your duck fat is solid, warm it in a microwave for a few seconds.
Add your sliced potatoes and one teaspoon of kosher salt.
Toss well making sure every slice is coated in fat.
Line a loaf pan with parchment paper.
Carefully layer potato slices, compressing layers and making sure there is duck fat between each layer.
Cover the top with parchment paper and place in a preheated 250℉ /120℃ oven and bake for three hours (or until a knife pierces through the middle very easily.)
Resting
Once the potatoes have finished baking, stack a second loaf pan on top of the parchment paper and weigh it down with some cans of food.
Place in the refrigerator to chill it for 12 hours.
Deep Frying
In a small saucepan, heat about an inch and a half of peanut oil to 375˚F/190℃.
While the oil is heating, unmold the layered potatoes and cut them into cubes.
With a large metal spoon lower potato stacks into the hot oil. You may have to gently nudge them off the bottom from time to time so they don’t stick.
Deep fry for 3-5 minutes or until they are golden brown.
Sprinkled with kosher salt and enjoy!
