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.
