Vegan Spanish Potato Tortilla

Instructions

1. The Potato & Onion Poach: Peel 1kg of Yukon Gold potatoes and slice into 1/8-inch half-moons. Finely dice 1 large yellow onion. In a 10-inch non-stick skillet, cover the potatoes and onions with 2 cups of extra-virgin olive oil. Poach over medium-low heat for 20 minutes until the potatoes are 'fork-tender' but not browned. Drain through a colander, reserving the flavored oil for later. This poaching step ensures the interior of your tortilla is silken and buttery.
   Expert Tip: The 'Starch Softening' Rule: By poaching in oil rather than boiling in water, you prevent the potatoes from becoming 'waterlogged.' This allows the chickpea flour batter to adhere better to the potato surfaces, creating a solid, sliceable cake rather than a loose scramble.
2. The Chickpea Emulsion: In a large mixing bowl, whisk 1.5 cups of chickpea flour with 1.5 cups of water and 1/2 tsp of turmeric (for color). Whisk vigorously until no lumps remain. Add 1 tsp of sea salt and a pinch of black salt (Kala Namak) if you want a subtle 'eggy' aroma. Let this mixture rest for 20 minutes while the potatoes cook.
3. The Hot-Marriage: Add the warm, drained potatoes and onions directly into the chickpea batter. Stir gently to coat every slice. The residual heat from the potatoes will begin to thicken the batter slightly, ensuring the vegetables stay suspended in the mixture rather than sinking to the bottom of the pan.
4. The Initial Set: Wipe out your skillet and add 2 tbsp of the reserved potato-oil. Heat over medium-high until shimmering. Pour the potato-batter mixture in and spread it flat. Shake the pan to ensure it doesn't stick. Reduce heat to medium-low and cook for 8-10 minutes. Use a spatula to occasionally 'tuck' the edges downward.
5. The Steam Trap: Cover the skillet with a lid for 3-4 minutes during the initial set. This traps steam, which helps the center of the chickpea batter cook through. Unlike eggs, chickpea flour needs consistent heat to lose its 'pasty' texture in the middle.
6. The Flip: Place a large flat plate over the skillet. Using oven mitts, quickly invert the pan. The tortilla should slide onto the plate. If the bottom is golden brown, it's ready. If it feels too soft, cook for 2 more minutes before attempting the flip again.
7. The Finish: Add 1 more tsp of oil to the pan and slide the tortilla back in (browned side up). Cook for another 5-7 minutes. Press down gently with your spatula; the tortilla should feel firm and 'springy' rather than squishy.
8. The Structural Rest: Slide the tortilla onto a board. You MUST let it rest for at least 15-20 minutes. As it cools, the chickpea starches 'retrograde' (firm up), which is what allows you to cut those perfect, clean triangular wedges. Serve with a side of vegan aioli.
