Brussels Sprouts belong to the group of cabbages. They actually look like miniature cabbages, but much smaller: typically 2.5–4 cm (0.98–1.6 in) in diameter. They grow like buds along the side of long, thick stalks. They are a winter vegetable, considered to be sweetest after a frost.
Brussel Sprouts are rich in mineral salts (phosphorus, copper, calcium, potassium, iron), vitamins (B6, K and C), fiber and antioxidants. Thay may potentially be useful in cancer prevention.
In cooking they are usually used to accompany meat dishes, or mashed with potatoes, cooked au gratin, or seasoned with metled butter.
