Cabidela

Cabidela or arroz de cabidela (cabidela rice) is a Portuguese dish made with poultry, usually a rooster (male chicken). It is typical of the northern Minho region. The particularity of the dish is that the hen's blood is added almost at the end, mixed with vinegar (to prevent clotting) while the rice is boiling, much like "jugged" or "civet" dishes. The blood is captured when the animal is slaughtered and imparts a brown color to the dish. Occasionally, white rice can be served with the dish, although this is not common. Cooking with blood is an antique custom common to several ancient cultures; in Portugal, cabidela has been in the written record since the 16th century and may be prepared as well with other fowl or animals (duck, turkey, pork, kid or game), though this is rare.
