Spanish Tortilla With Sweet Potatoes Recipes

Steps:

• Peel and thinly slice the potatoes. Soak slices in water for 10 minutes. Drain and dry completely in a salad spinner. Meanwhile, pour enough olive oil into a large saucepan so it's about an inch deep. Heat over medium heat until a slice of onion bubbles gently when placed in the oil, about 310 degrees F. Add the onions and fry, stirring occasionally until just golden, about 8 minutes. Scoop the onions from the oil with a slotted spoon and drain on a paper-towel lined baking sheet.
• Add about half of the potatoes, and fry until lightly golden and a little puffy, about 10 minutes. Scoop the potatoes from the oil, add to the onions. Repeat with the rest of the potatoes. Reserve the oil. Season the vegetables with 3 teaspoons of the salt. (The preparation of the vegetables can be done up to 2 hours ahead.)
• Break the eggs into a large bowl. Whisk just enough to combine but not so much that they get loose and runny, about 15 times. Add the vegetables and remaining 1 teaspoon salt.
• Heat a medium (10-inch) nonstick skillet over medium heat. Add 2 tablespoons of the reserved oil and heat. Add the tortilla mixture and stir briskly with a spatula to get peaks and valleys in the folds of the egg, about 2 to 3 minutes. Stop stirring and reduce the heat to low, cover and cook until the eggs are set but still pretty loose, about 5 minutes. Lay a flat pan lid or a plate on top and invert the tortilla. Add more oil to the pan if needed, and slide the tortilla back into the pan, cover and finish cooking until set and lightly brown, about 3 minutes more. Slide the tortilla out of the pan to a cutting board to cool slightly.
• Cut into cubes or thin wedges and serve warm or room temperature as is or with 1 of the suggested toppings.
• Heat the olive oil in a medium skillet over medium heat. Add the onions and sugar and half the salt. Cook, stirring occasionally, until golden and sweet, about 1 hour. If the onions begin to get really brown, add a splash of water to slow them down.
• Meanwhile, cut the tomatoes, crosswise. Grate them on the cut side on the largest holes of a box grater into a bowl all the way down to the skins. Discard skins. Add tomato puree, pimenton and bay leaf to the caramelized onions, and continue to cook until quite thick and the tomato separates from the oil, about 10 to 15 minutes more. Season with the remaining salt or to taste. Serve warm or at room temperature.

Steps:

• Put the spinach in a large colander and pour over a kettleful of boiling water. Drain well and, when cooled a little, squeeze dry, trying not to mush up the spinach too much.
• Heat 3 tbsp oil in a 25cm non-stick pan with a lid, then sweat the onions for 15 mins until really soft but not coloured. Add another 3 tbsp oil and add the potatoes and garlic. Mix in with the onions, season well, cover and cook over a gentle heat for another 15 mins or so until the potatoes are very tender. Stir occasionally to stop them catching.
• Whisk the eggs in a large bowl, tip in the cooked potato and onion, and mix together. Separate the spinach clumps, add to the mix and fold through, trying not to break up the potato too much.
• Add 2 tbsp more oil to the pan and pour in the sweet potato and egg mix. Cover and cook over a low-medium heat for 20 mins until the base and sides are golden brown and the centre has mostly set. Run a palette knife around the sides to stop it from sticking. 5 To turn the tortilla over, put a plate face down onto the pan, then flip it over. Slide the tortilla back into the pan and cook for a further 5-10 mins until just set and golden all over. (Don't worry if it breaks up a little on the edges as you're turning it - it will look perfect when it's cooked through and set.) Continue cooking on the other side until just set and golden all over. Again use a palette knife to release the tortilla from the sides. Allow to rest for 5 mins, then tip onto a board before cutting into wedges.

Steps:

• Put a large non-stick frying pan on a low heat. Cook the onion slowly in the oil and butter until soft but not brown - this should take about 15 mins. Meanwhile, peel the tomatoes (if using) by scoring the skins with a cross, putting them in a bowl and pouring over just-boiled water. Drain the water after 2-3 mins and the skins will peel away easily. You can then coarsely grate them.
• Add the potatoes to the pan, then cover and cook for a further 15-20 mins, stirring occasionally to make sure they fry evenly. When the potatoes are soft and the onion is shiny, crush 2 garlic cloves and stir in, followed by the beaten eggs.
• Put the lid back on the pan and leave the tortilla to cook gently. After 20 mins, the edges and base should be golden, the top set but the middle still a little wobbly. To turn it over, slide it onto a plate and put another plate on top, turn the whole thing over and slide it back into the pan to finish cooking.
• Once cooked, transfer to a plate and serve the tortilla warm or cold, scattered with the chopped parsley. To accompany the tortilla, take slices of warmed baguette, stab all over with a fork and rub with the remaining garlic, pile on the grated tomatoes and season with sea salt and a drizzle of olive oil.

Steps:

• Peel and thinly slice potatoes and onions; it's easiest if you use a mandoline. Meanwhile, heat oil in an 8- or 10-inch nonstick skillet over medium heat. After 3 or 4 minutes, drop in a potato slice. When tiny bubbles appear around its edges, add potatoes, onions, a good pinch of salt and a liberal sprinkling of pepper. Gently turn mixture in oil with a wooden spoon, and adjust heat so oil bubbles lazily.
• Cook, turning potatoes gently every few minutes, until they are tender when pierced with a small knife. Adjust the heat so they do not brown. If potatoes begin to break, they are overdone; stop cooking immediately. As potatoes cook, beat eggs with some salt and pepper in a large bowl.
• Drain potatoes in a colander, reserving oil. Wipe out skillet, and heat over a medium flame for a minute. Add 2 tablespoons oil. Gently mix warm potatoes with eggs, and add to skillet. As soon as edges firm up, after a minute or so, reduce heat to medium-low. Cook 5 minutes.
• Insert a rubber spatula all around edges of tortilla to make sure it will slide from pan. The top will still be runny. Carefully slide out onto a plate. Cover with another plate, and holding plates tightly, invert them. Add another tablespoon oil to skillet, and use the spatula to coax tortilla back in. Cook 5 minutes, then slide from skillet onto a clean plate. Serve warm (not hot), or at room temperature. Do not refrigerate.
