Boudin noir

Black pudding is a famous British delicacy made from animal blood (usually from pigs), oats, and fat. The combined ingredients are stuffed into a casing, and the sausage can then be fried, grilled, boiled, sliced, or crumbled. In Manchester, it is traditionally boiled and served with vinegar, while in other parts of the country, it is often a part of the traditional full English breakfast.
