Croquettes à la cecina

Croquetas con cecina is a traditional croquette variety. It's usually made with a combination of butter, leeks, cecina (air-dried beef), milk, flour, salt, pepper, nutmeg, eggs, breadcrumbs, and olive oil. The leeks and cecina are sautéed in butter, seasoned with salt and pepper, and then mixed with a bechamel sauce consisting of flour, butter, milk, salt, pepper, and nutmeg. The mixture is chilled, shaped into croquetas, dipped in eggs, rolled in breadcrumbs, and then fried in olive oil until golden brown.
