Originating from Vega de Aranjuez, San Martín de la Vega, and Ciempozuelos, the yellow onion is valued for its versatility in cooking. This extra onion variety is characterized by its strong flavor, and although its interior is white, it presents light yellow layers that stand out. Its use is practically indispensable in the preparation of sofritos, which form the basis of many traditional dishes in Spanish cuisine. The yellow onion is ideal not only for stews but also for salads and other preparations requiring a strong flavor. This onion exemplifies high-quality national cultivation, ensuring freshness and flavor in every bite.
