Onions are endlessly versatile and an essential ingredient in countless recipes. Varieties of onion differ in size, strength and colour. The yellow onion is the most commonly known variety – it has pale golden skin, greenish-white flesh and a strong taste. Red onions are an attractive, milder alternative to the yellow onion with their shiny purple skin and red-tinged flesh.
