Edible Memory

Book excerpt: Jordan begins with the heirloom tomato, inquiring into its botanical origins in South America and its culinary beginnings in Aztec cooking to show how the homely and homegrown tomato has since grown to be an object of wealth and taste, as well as a popular symbol of the farm-to-table and heritage foods movements. She shows how a shift in the 1940s away from open pollination resulted in a narrow range of hybrid tomato crops. But memory and the pursuit of flavor led to intense seed-saving efforts increasing in the 1970s, as local produce and seeds began to be recognized as living windows to the past.
