Croquetas caseras de spinacas

Croquetas caseras de espinacas is a traditional croquette variety. It's usually made with a combination of spinach, butter, salt, flour, milk, crumbled blue cheese, eggs, breadcrumbs, and olive oil. The spinach is cooked, drained, sautéed in butter, and then mixed with the flour and milk until a creamy sauce forms. The crumbled cheese is added to the hot sauce until it melts. The mixture is chilled, shaped into croquetas, dipped in eggs, rolled in breadcrumbs, and then fried in hot olive oil until golden brown.
