The first collaboration book by Keiichiro Koyama of NEWS and the popular cooking expert Mikimama, who are actual sister and brother! This is the book edition of "Koyama Kyodai no Shokutaku," the popular series on Lettuce Club WEB in which the popular cooking expert Mikimama passes on her recommended recipes to Keiichiro Koyama, who loves to eat but is a beginner at cooking. It carries about 50 "easy home cooking recipes" that an older sister wants to pass on to her younger brother. It introduces easy, low-cost and time-saving recipes that even beginners at cooking can make, such as "winged gyoza," "15-minute just-cook paella" and "uni-flavored pasta made without uni," which are Mikimama's arrangements of the flavors remembered in the Koyama family. For this book edition there are also plenty of newly shot photo pages visiting places full of memories, such as the Chinese restaurant at the family home of the two and the park where they played as small children, along with treasured photos from their childhood! This is a book that tells the whole history of the Koyama family.
