Lettuce Hearts: A Healthy and Versatile Delight
Lettuce hearts are dwarf romaine lettuces about 10 cm tall, resembling cabbage in appearance. They are cultivated in the Navarrese municipality of Tudela and the surroundings of the Ebro River throughout the year, both outdoors and in greenhouses. They are characterized by being tight, tender, and having thick, strong, and very rough leaves, with a developed central vein. The color varies from the yellow of their interior to the light green of the outer leaves. Lettuce hearts are a good source of vitamins A, C, and K, folic acid, iron, and potassium. They also contain fiber and antioxidants that can help prevent cellular aging and some diseases. Additionally, they are low in calories and have a high water content, making them ideal for weight loss diets and for hydration. Lettuce hearts can be consumed raw or cooked. Raw, they are usually cut in half or quarters and seasoned with oil, vinegar, and salt, or with more elaborate vinaigrettes that can include capers, anchovies, nuts, mustard, honey, raspberries, etc. They can also be filled with cheese, smoked salmon, ham, beets, or whatever you prefer. Cooked, they can be briefly grilled to brown the outside but maintain their texture inside. They can be accompanied by salmon, peppers, tomatoes, or hot vinaigrettes. Another way to eat them is to use the leaves as tacos or boats to fill them with rice, smoked tofu, avocado, or whatever you desire.
