Lemons get a twist in Hiroshima - SilverKris

"A return-to-the-land citrus operation on a nearby island that pioneered a labor-intensive technique for producing novelty heart-shaped lemons: the grower devised vice-like metal moulds with a local metalworks and adjusts them throughout the season, tending each fruit by hand. Despite losses from trial and error, the farm now produces about 3,000 heart-shaped lemons annually and sells them across the region — in Hiroshima and Miyajima — in Tokyo and even overseas in Taiwan." - Tom Miyagawa Coulton
