The sweet onion is a traditional and versatile food in Mediterranean cuisine. Originating from Spain, this onion is known for its mild and sweet taste, which is recommended to be consumed raw to fully enjoy its properties and benefits. With a medium size, it is rich in vitamins A, B1, C, and E, as well as minerals and folic acid. The latter component is responsible for the irritation we feel when cutting it. The sweet onion is not only a delicious ingredient but also possesses tonic, diuretic, and purifying properties.
