One of our most cherished and popular greens, spinach is a superfood beyond compare. And while its iron content has been endlessly debated, it has virtues far beyond that which made Popeye such a strapping sailor-man. Spinach is an excellent source of vitamin A, and a good source of vitamin C and folate; and importantly, it's readily available. You will find spinach in a range of textures, from small, smooth baby leaves to large, thick and crinkled mature leaves; and it is available year-round. Young leaves are mild and tender and are good for salads or quick sautés, while tougher leaves are abundant in flavor and have a great chewy texture. Look for firm, deep green leaves – without spots or blemishes. Sand and dirt love to hide in spinach’s many nooks and crannies, so use several water baths or rinses to remove all grit.
