Bring a large pot of water to a steady boil, then stir in the kosher salt and white vinegar. Add the russet potatoes and cook until the edges are just tender while the centers still offer slight resistance, about 7 to 9 minutes after the water returns to a simmer. The vinegar helps the potatoes hold their shape during frying without affecting the flavor.
1 tbsp (18 g) kosher salt, 2 tbsps (30 ml) white distilled vinegar, 2 lbs (907 g) russet potatoes
Drain the potatoes and spread them in a single layer on a wire rack set over a sheet pan. Let them steam-dry until the surface looks dry and matte. Removing the surface moisture helps the potatoes crisp more efficiently during frying.
While the potatoes dry, warm the olive oil in a skillet over medium heat. Add the onion and cook until softened, then stir in the garlic and cook for about 30 seconds until fragrant. Add the tomato paste and cook for 1 minute, stirring frequently, until it darkens slightly. Stir in the smoked paprika, cayenne, kosher salt, and black pepper, cooking for another 30 seconds to bloom the spices without letting them scorch.
2 tbsps (30 ml) olive oil, ½ cup (80 g) finely chopped yellow onion, 4 cloves garlic, 1 tbsp (16 g) tomato paste, 1 tbsp (7 g) smoked paprika, ¼ tsp (0.5 g) cayenne pepper, ½ tsp (3 g) kosher salt, ¼ tsp (0.6 g) black pepper
Pour in the tomato sauce, red wine vinegar, and broth. Reduce the heat and simmer for 4 to 5 minutes, stirring occasionally, until the flavors come together. Blend the sauce with an immersion blender if you prefer a smooth consistency, or leave it slightly chunky for a more rustic presentation. Taste and adjust the seasoning with additional salt, black pepper, cayenne, or vinegar if needed.

Heat the canola oil to 350°F (175°C) in a heavy pot or Dutch oven. Fry the potatoes in batches for 7 to 10 minutes, turning occasionally, until browned and crisp on the outside with tender centers. Avoid overcrowding the pot, as this lowers the oil temperature and prevents proper browning.

Transfer the fried potatoes to paper towels or a wire rack to drain briefly, then season with a pinch of kosher salt while they are still hot.
Arrange the potatoes on a serving platter and spoon the warm bravas sauce over the top. Drizzle generously with garlic aioli, sprinkle with chopped fresh parsley, and serve immediately while the potatoes are at their crispiest.
