Washington is sweet on Walla Walla sweet onions. In fact, these globes of goodness serve as the official state vegetable. They’re mild, yet still deliver great onion flavor without any of the bite (or tears) of other onions. They also provide a healthy dose of vitamin C. The Walla Walla onion is called ‘sweet’ because of its more mild flavor — a result of the low sulfur content of the soil in which they’re grown, explained Elizabeth Hulbrock, a WIC (Women, Infants, and Children) dietitian and coordinator for Kaiser Permanente. “The low sulfur content results in an onion with less pyruvic acid, which is responsible for an onion’s pungency,” Hulbrock said, adding that Walla Walla onions are also juicier thanks to their higher water content. Look for sweet onions with firm necks, and flesh with no bruising. Store uncut onions at room temperature for 3 to 4 weeks.
