What is Romesco?
Romesco is a sauce with a base of roasted tomatoes and garlic, blended with nuts such as almonds, hazelnuts, or pine nuts. It also includes olive or sunflower oil, and nyora peppers, a small sun-dried red pepper. The sauce is often thickened with stale bread or flour, and vinegar adds a tangy note. Its texture can range from smooth to chunky, and it is usually a deep reddish color. The taste is rich, slightly sweet from the peppers, nutty, and tangy.
Where does Romesco come from?
Romesco comes from Valls in the Catalonia region of Spain. It was first made by local fishermen, who created the sauce to pair with fish. Over time, it spread throughout Catalonia and became a staple in the region’s cooking. There is no single standard recipe, and variations have developed in different towns and families. The sauce is now a well-known part of Catalan food culture.
How is Romesco made?
To make romesco, tomatoes and garlic are roasted, then combined with toasted nuts such as almonds or hazelnuts. Nyora peppers, which are sun-dried and mild, are soaked and added for flavor and color. The mixture is blended with oil, vinegar, and sometimes thickened with stale bread or flour. Some versions use pine nuts or even almond biscotti, and herbs like fennel or mint may be added, especially when served with fish.
How and when is Romesco eaten?
Romesco is most often served as a sauce for seafood, but it also goes well with vegetables, poultry, and red meats like lamb. It is used as a dip or spooned over grilled or roasted foods. In Catalonia, it is a common accompaniment at meals and can be found in both home kitchens and restaurants. The sauce is sometimes confused with similar local sauces, but romesco is distinct for its use of dried peppers and nuts.
Kinds of Romesco
There are many versions of romesco. Some are thick and chunky, while others are smooth and pourable. The choice of nuts can vary, with some cooks using hazelnuts instead of almonds. In some places, almond biscotti and hard-boiled eggs are added. The sauce may also be adjusted with different vinegars or herbs, and each family or town may have its own preferred method.
