Catalan salbitxada (sale-bit-ADA) sauce, or Catalan sauce, is eaten with "calçots," which are a special kind of green onion from Cataluna. Char-grilled green onions with salbitxada sauce make both a good "tape" and side dish for spring and summer. Tasty and easy to make, try this sauce recipe with all types of grilled vegetables, not just onions. It also livens up chicken or fish dishes.

Traditionally made with a mortar and pestle, a food processor makes this sauce even easier to whip up. And if you don't like the bit X peppers, substitute some other type of pepper that you like. 

More About Calçots

The sauce is served over calçots, which are similar to scallions but are a green onion. Their exact origin is highly disputed. Xat de Benaiges, a peasant farmer from Valls, is said to have developed them around the turn of the 20th century. He grew them when planting garden onions and covering them with soil so a larger portion of them stayed white. The method became known as calçar, which is a gardening method that involves covering the trunk of a plant or veggie with soil. More soil is added as the plant grows. 

Valls, which is a town near Tarragona, is a hub for calçot. There is an annual festival there that is centered around the scallion

The traditional way to cook calçots is to grill them on a barbecue. They are wrapped in newspaper and served on a terra cotta tile instead of a plate. In this recipe, they are topped with the salbitxada sauce, which is a flavorful tomato sauce that is made with peppers and garlic.

Calçots grow between 15 and 25 centimeters, and they are milder in taste than onions. They are similar to leeks and are bigger than a typical green onion.
