"Cauliflower," wrote Mark Twain, "is nothing but cabbage with a college education." Cauliflower is a cool season vegetable in the cruciferous vegetable family, which includes cabbage, broccoli and collards. White cauliflower is the most familiar, but other varieties come in green and even purple. Cauliflower is high in vitamin C, potassium, fiber and other nutrients. According to Washington State University, freezing is the preferred way to preserve cauliflower. Other methods include pickling and dehydrating. Pressure canning is not recommended.
