1 1/2 pounds russet potatoes, washed
1 tablespoon neutral oil
1/2 teaspoon salt
1/4 teaspoon black pepper
Bring a large pot of water to a boil, and add the unpeeled potatoes. Cook for 20 minutes, or until just cooked but still firm. Drain, rinse under cold water, and chill until cold, about 1 hour. (This step can be completed in advance!)
When ready to bake, preheat the oven to 425 degrees. Peel and grate the potatoes, then toss with the oil, salt, and pepper.
Divide the potato mixture evenly among 12 muffin tin cups. Press down, forming the mixture into a cup that extends past the rim. (Be sure to leave the bottom quite thick to ensure that it holds together.)
Bake for 30-35 minutes, until nice and golden brown.
Remove from the oven and allow to cool completely before adding topping of choice. (The nests can be reheated in the oven just before serving, if you like!)
Pro-Tip: Top with fried egg, cut in circular shape around yolk.
