Spinach is an emblematic vegetable, known for its versatility and high nutritional value. Originating from the Vega de Aranjuez, particularly from San Martín de la Vega and Ciempozuelos, these green leaves are an excellent source of vitamins such as C and E, as well as minerals like iron and calcium. Spinach is perfect for salads, smoothies, or cooked dishes like sautéed spinach with ham and pine nuts. To preserve freshness, it is essential to store them properly in the refrigerator and consume them within two days. When preparing, you can boil, sauté, or consume them raw after washing thoroughly. Remember that washing can be done either in a bowl of water or leaf by leaf under the tap to ensure cleanliness. Enjoy these leaves for healthy and delicious recipes.
