Tearless onions are to go on sale at Waitrose, reported The Times. Rick Watson, a plant breeder, began working on the innovation in the late 1980s, using natural techniques rather than genetic modification to create the unique variety. Onions normally make people cry because when they are sliced they release synpropanethial-S-oxide, which irritates glands in the eyes. A taste tester said tearless onions were “sweet enough that you could sit there and eat them like popcorn, if you were inclined to do such a strange thing”.
