Cornell Researchers Develop New Mild Onions Offering Great Taste, Long Shelf Life

Cornell researchers have developed new mild onions that will have chefs crying – tears of joy. Twelve years in development and with a couple years of testing to go, researchers say it will be just a few years before the mild locally grown onions are available to the public.

“These onions have a longer shelf life and still produce huge flavors; I see them as being a consumer’s dream,” said Steve Miller, Cornell Dining senior executive chef, who with a Wegmans supermarket executive chef has tested about a dozen of the experimental onion hybrids.

In general, current mild onions are watery and soft due to low sugar content (called low brix), which leads to a short shelf life and makes them mushy when cooked. Longer-lasting pungent onions are higher in sugar and caramelize when cooked, but reducing their bite requires more cooking, which also softens them.
