Joe Regenstein, professor of food science at Cornell and director of the Cornell Kosher and Halal Food Initiative, tells the story of how Nabisco's famous Oreo cookie was converted into a fully orthodox kosher product.

The costly transformation, which took more than three years, began when the country's major ice cream companies--most operating under kosher standards--wanted to make a product with authentic Oreos.

The event was part of Cornell's Jewish Faculty Lecture Series, sponsored by Cornell Hillel and supported by the Einhorn Family Charitable Trust.
