General Information:
Red Onions tend to be medium to large in size and have a sharp flavor and eye-watering qualities. They are often consumed raw (and can be added to salads for colour and bite), grilled or lightly cooked with other foods. Red onions are available throughout the year and are high in flavonoids and fibre (compared to white and yellow onions). Cut red onion can be soaked in cool water for a period of time and the water can be drained off, resulting in less “bite” and pungency.
