What is the Confection “Geppei”?
Actually, I totally thought that the confection Geppei was a type of Wagashi, because it is almost always lined up with Wagashi confections like Manju and Momoyama.
But I looked up “月餅” on Wikipedia Japan and found my thought was incorrect. The article says that the confection Geppei is a type of Chinese confection and was introduced from China to Japan.
In 1927, a Japanese confectionery company “Nakamuraya (中村屋)” altered the original Chinese Geppei and developed a Japanese-Style one to suit Japanese tastes. Now the Japanese Geppei cake has been popularized and can be found in many grocery stores around the country.
It seems that in China the confection Geppei comes in many varieties and various fillings, but those have a round flat shape like a full moon in common as the word “月” means the moon.
Japanese-Style Geppei are also shaped like a full moon, but most are filled with a sweetened Azuki red bean paste. The Japanese Geppei cake is similar to Manju buns in composition and taste, but isn’t fluffy at all.
Finally, according to the ingredient list, this Yamazaki’s Geppei snack cake is made mainly with sweet red bean paste, wheat flour, egg yolk, sugar, whole egg, lard, sweetened white bean paste, starch syrup, mirin, soy sauce, egg white, and butter.
