Romesco sauce is a flavorful Spanish condiment originating from the Catalonia region. It is primarily made from roasted red peppers, tomatoes, garlic, almonds, and olive oil, blended together to create a rich, thick sauce. The combination of ingredients gives it a unique taste that balances sweetness, smokiness, and nuttiness. Traditionally, romesco sauce is served with seafood, grilled vegetables, or meats, enhancing the flavors of the dishes. It can also be used as a dip or spread, making it a versatile addition to various meals. Its vibrant color and robust flavor make it a popular choice in Mediterranean cuisine.
