While many of us prefer eggs with deep coloured yolks, people in Japan like to have eggs with whiter interiors. To keep the ‘egg lovers’ happy, farmers in Japan are constantly trying to rear chicken that lay eggs with white yolks. Eggs with yellow yolks usually get their colour from chicken feed that’s made of imported corn. The eggs, which are laid by rice-fed hens, owe their unusual colour to the diet of the chicken. These eggs are known as Kometsuya—a combination of Japanese words kome (rice) and tsuya (luster). Several chicken farms have already started transitioning their birds to feed that is mostly produced locally, reported the Japan Times. “In the not-too-distant future, white sunny-side ups will be part of the daily cuisine for Japanese,” says an official of Hokkaido Dosanko Plaza shop in Japan.
