Smoky, spiced Romesco Sauce is about to change your life - and just about anything on your plate. Start by roasting nuts until fragrant. Add them, along with tomatoes, red peppers, garlic and seasoning to your food processor or blender, and pulse until all ingredients are pulverized. Turn power to steady and slowly add olive oil. Blend until smooth, adjust to taste, and serve or store immediately.
Heat the oven to 350°F. Spread the nuts onto a baking sheet in a single layer. Transfer to a food processor and toast 8-10 minutes, shaking once halfway through, or until the nuts are lightly browned and very fragrant. Remove from the oven and cool slightly.
Place the tomatoes into a colander and rinse under cool running water to remove the canning sauce.
Place the tomatoes, roasted red pepper, nuts, vinegar, galic, paprika, chili powder and salt in the bowl of a food processor or blender. Pulse until all ingredients are pulverized.
Switch the motor to continuous - pour the olive oil through the feed tube.
Taste for seasoning and adjust seasonings or acidity to taste. Serve immediately, or store in the fridge in a sealed jar for up to 1 week. Makes about 2 cups.
