Patatas Bravas

Directions

Sauce

1Heat oil in small saucepan over medium-low heat until shimmering. Add garlic, paprika, salt, and cayenne and cook until fragrant, about 30 seconds. Add tomato paste and cook for 30 seconds. Whisk in water and bring to boil over high heat. Reduce heat to medium-low and simmer until slightly thickened, 4 to 5 minutes. Transfer sauce to bowl, stir in vinegar, and let cool completely. Once cool, whisk in mayonnaise. (Sauce can be refrigerated for up to 24 hours. Bring to room temperature before serving.)

Potatoes

1Bring 8 cups water to boil in large saucepan over high heat. Add potatoes and baking soda. Return to boil and cook for 1 minute. Drain potatoes.

2Return potatoes to saucepan and place over low heat. Cook, shaking saucepan occasionally until any surface moisture has evaporated, 30 seconds to 1 minute. Remove from heat. Add 1½ teaspoons salt and stir with rubber spatula until potatoes are coated with thick, starchy paste, about 30 seconds. Transfer potatoes to rimmed baking sheet in a single layer to cool. (Potatoes can stand at room temperature for up to 2 hours.)

3Heat oil in large Dutch oven over high heat to 375 degrees. Add all potatoes (they should just be submerged in oil) and cook, stirring occasionally with wire skimmer or slotted spoon, until deep golden brown and crispy, 20 to 25 minutes.

4Transfer potatoes to paper towel–lined wire rack set in rimmed baking sheet. Season with salt to taste. Spoon ½ cup sauce onto bottom of large platter or 1½ tablespoons sauce onto individual plates. Arrange potatoes over sauce and serve immediately, passing remaining sauce separately.
