A couple of years ago if someone told you that your blueberries were loaded with anthocyanins, you'd probably have dumped the bowl down the garbage disposal and called 911 to report being poisoned.
Anthocyanin sounds scary, kind of like cyanide. Fortunately it's a good word; "anthocyanin" is derived from two Greek words, "anthos " (flower) and "kyanos" (blue). It makes sense, therefore, that anthocyanin pigments are responsible for the blue, purple, and red color of many fruits, vegetables, and flowers.
When it comes to food, anthocyanins are little health workhorses. They're associated with a decreased risk of many illnesses including cancer, high blood pressure, and even Alzheimer's. Fruits and vegetables that are brightly colored are even better for you. That helps explains why pomegranates, blueberries, broccoli, and red grapes are on virtually every Top 10 Healthiest Foods list ever written.
Purple cauliflower, which is currently in season, owes its stunning color to anthocyanins. This cheeky variety, along with its cousins, orange and green cauliflower, have helped make cauliflower fashionable.
Use purple cauliflower in cooking as you would use white cauliflower. Steam, saute, bake, or roast it; just don't overcook it, or you'll risk mushiness. If you boil it, add a few drops of vinegar to the water to help maintain its vivid color. The texture is the same as white cauliflower although the flavor is slightly sweeter.
One of my favorite ways to enjoy purple cauliflower is in winter salads like this Roasted Purple Cauliflower and Arugula Salad. Roasted purple cauliflower and peppery arugula are dressed in a light and refreshing lemon-mustard-rosemary vinaigrette. The flavors match the vegetables' brilliant color making this a winter salad guaranteed to brighten any cold, gray day.
