Don’t cry baby, it’s sweet onion season. Walla Walla sweet onions became Washington’s official state vegetable in 2007 thanks to a dedicated group of junior high students who lobbied the state legislature. A soldier named Peter Pieri is credited with bringing sweet onion seeds to Washington from the island of Corsica in the
1880s. Sweet onions have a very low amount of pyruvic acid which is the compound that makes you cry and gives onions their pungent bite. This favored allium is also 95 percent water which means they have to be harvested by hand as they are much more delicate than their regular onion brethren. Their shelve life is shorter too, usually only available from mid-June to late August.
