Cauliflower lacks the green chlorophyll found in other members of the cruciferous family of vegetables like broccoli, cabbage and kale, because the leaves of the plant shield the florets from the sun as they grow. We tie up the heads early in the fall to protect the head. Cauliflower has a compact head (called a "curd"), usually about six inches in diameter that is composed of undeveloped flower buds. The flowers are attached to a central stalk.
Place in a plastic bag and store in your refrigerator crisper. When stored properly, cauliflower will last up to five days; however, it is best when eaten within three days.
