LA TORTILLA DE PATATA RECIPES

Steps:

• Halve the potatoes lengthwise and, with a sharp knife or, preferably, a mandoline, slice them crosswise about 1/16 inch thick. Toss the potatoes with 1/2 teaspoon of the salt and half of the pepper. In 9 inch castiron skillet, heat 1/4 cup of the olive oil over medium heat. Add the potatoes and cook, tossing occasionally with a spatula, until golden and crisp. Try to avoid clumping but, if they stick together a bit don't worry. Set the pan aside.
• Heat 2 tablespoons of the olive oil in another skillet over medium low heat and saute the onions, stirring occasionally, for about 20 minutes, or until very soft and slightly golden.
• Preheat the oven to 350 degrees. In a large bowl, beat the eggs together and stir in the remaining 1/4 teaspoon each of salt and pepper, and the onions. Remove the potatoes from the pan with a slotted spoon and let them drain for a moment in a colander. Wipe the potato cooking pan with a paper towel, then add the remaining 2 tablespoons oil to the skillet. Heat the skillet over low heat, stir the potatoes into the egg mixture, and immediately pour it into the hot skillet. Cook for about 8 minutes, or until the bottom of the cake is slightly golden. Place a large plate upside down on top of the skillet, invert it, and turn the cake onto the plate. Slide the cake back into the pan. Finish cooking in the oven for 4 to 5 more minutes, or until the eggs are set. Cool in the pan for 5 minutes, then cut into wedges or squares, depending on the number of people you want to serve. Serve warm or at room.

Steps:

• Heat oil in a deep stockpot over medium-high heat until almost smoking, 2 to 4 minutes. Add potatoes and onion; they should be mostly covered with oil. Season with 1 1/2 teaspoons salt. Cook, stirring occasionally and maintaining a gentle simmer, until potatoes are just fork-tender, 8 to 12 minutes; do not overcook.
• Drain potato-onion mixture in a colander; reserve oil for another use or discard. Allow to cool for a few minutes, then taste and season with more salt, if needed.
• Meanwhile, crack eggs into a large bowl and season with remaining 1/2 teaspoon salt; whisk until well beaten. Add potato-onion mixture and toss to coat.
• Heat a 10-inch nonstick skillet over high heat. Add 1 teaspoon olive oil, then pour in egg-potato mixture. Level it with a spatula and cook for 1 minute. Reduce heat to medium-low and cook for about 5 minutes. Run a rubber spatula around the outer edges to make sure it's not sticking and to help it form its shape.
• Once it starts to firm up around the edges and in the center (although it will still be a little runny), place a large plate over the skillet. Flip the omelet onto the plate, then slide it back into the skillet. Use the spatula to help press the edges in and under, to maintain a rounded edge. Cook over high heat for 1 minute, then reduce to low and cook until it feels set in the center and a knife inserted in the center comes out clean, 2 to 3 more minutes.
