Where It Grows
Red onions are a versatile crop that can grow in both temperate and tropical climates. They thrive in well-drained, sandy, and loamy soils with a pH between 5.5 and 6.5. Red onions are often grown in the cooler regions of the world due to their preference for cooler weather during growth and development. They are grown extensively in the United States, particularly in California, Texas, and Oregon. Other major producers include India, China, and Egypt. The cultivation period typically lasts for 90 to 120 days.
Best Way to Eat
Red onions can be consumed both raw and cooked, though different preparation methods can affect their nutritional content and flavor. When eaten raw, such as in salads or sandwiches, they provide a crisp texture and sharp flavor. Cooking red onions can mellow their flavor, making them a great addition to stir-fries, roasts, and grilled dishes. To retain the most nutritional benefits, it is best to eat red onions raw or lightly sautéed. Overcooking can lead to loss of some nutrients, particularly vitamin C and B vitamins. For maximum flavor, store red onions in a cool, dry, well-ventilated place away from direct sunlight.
