Tetsuo ENDO wrote in his book, "Bukkake-meshi no Etsuraku" (The Joys of Bukkake Rice) (the title was revised to "Shirukake-meshi Kaishokugaku" (juice run meal for library) for the pocket edition), that the reason why curry and rice has become so popular is that the dish was regarded as a descendant of 'bukkake meshi' (literally meaning sloshed onto rice).
なお、遠藤哲夫は著書『ぶっかけめしの悦楽』（文庫版改題『汁かけめし快食學』）で、日本においてこれほどまでにカレーライスが普及したのは、日本の伝統食である「ぶっかけ飯（汁かけ飯）」の系譜にカレーライスが位置づけられたためだと述べている。
