Calcotada Onions

Calçotada The Spanish Green Onion Festival

My friend, TJ, recently visited Spain, and while he was there he attended calçotadaCalçotada is a green onion festival that attracts thousands of visitors each spring to the Catalonia region.

Calçots, small, flavorful green onions, are grilled on a flaming barbeque until they are blackened and tender and then served with a variety of popular Spanish dipping sauces on the side.  The eaters peel away the blackened skin and enjoy these barbequed onions by the dozen.

This past week, our culinary team has been grilling calçots at the Kendall-Jackson Wine Center with the fresh green onions from our garden.  They have been extraordinary.  After being grilled over an open flame the green onions become mild and sweet with a slight smoky flavor.

We serve ours with a savory romesco sauce on the side which also adds a bit of spice.  These grilled green onions are wonderful paired with a smooth red wine, such as the Kendall-Jackson Vinter’s Reserve Merlot.  Below is our recipe for Calçots with Romeso Sauce.  Enjoy!
