A while ago some romance readers/authors decided to write a parody romance set at "the most important hummus industry conference of the year" so I was rather amused to discover a real romance novel which, apparently, has a "macaroni magnate" as its hero.
It's a Harlequin Temptation published in September 1986 and for all I know, it's a deliciously spicy read. I'm still amused that someone got the words "macaroni magnate" into this blurb.
