Transfer to a pan and cook until the crotons are lightly browned and crisp (about 15 minutes). Remove from the pan and add a further 1 tbsps of finely grated Parmesan and stir. Set it aside to cool.
Mix the egg yolk, lemon juice, anchovy, Worcestershire sauce, salt, garlic, and Extra Virgin Olive Oil from Spain. Blend it with a hand-held mixer, food processor or blender.
