Cauliflower contains a high amount of vitamin C, folate, fiber and complex carbohydrates. Steaming and blanching are the best methods to preserve the most flavor and nutrition. Store in perforated plastic bags for 5 to 7 days and hold off on washing it until use.Use it in a cauliflower-based pizza crust, roast florets or the whole head, chop it finely into "rice," or deep fry it. It can be transformed into almost anything, taking on the flavors or sauces and spices very well.
