Corn Nuts (later CornNuts) were invented by Albert Holloway in 1936 1, and called them "Olin's Brown Jug Toasted Corn". Beginning in approximately 1948, CornNuts were manufactured in a relatively small factory in the South Stonehurst neighborhood at 10229 Pearmain Street; the building still exists.
Corn Nuts are made by soaking corn kernels in water to rehydrate them, then deep-frying them, though ads refer to them as "lightly toasted". There are similar snack foods in Central and South America.
The company was owned by Holloway's family until 1998, when it was purchased by Nabisco and merged into Nabisco's Planters subsidiary. Since 2007, CornNuts, Planters and Nabisco have all been part of Kraft Foods.
