Fresh spinach features tender, dark green leaves with a mild, slightly sweet flavor. It is commonly sold as bunches or pre-washed bags and used raw in salads and sandwiches, blended into smoothies, or cooked into sautés, quiches, soups, and casseroles. Store refrigerated and use within several days for best texture and flavor. Wash thoroughly if not pre-washed, and remove any wilted leaves before preparing.
