I apologize in advance for the quality of the mages in this post - but this was the only form I could find these horrendous recipes in (lifted from a Facebook page which features Godawful cookbooks from the past 100 years or so).
This is the kind of thing women were told to do in the 1950s, and - as we too often forget - well into the '60s. To "keep your man" (i. e. not allow him to stray sexually), you had to satisfy "that other appetite" - an idea as old as Betty Crocker herself. Just the assumption that you "caught" him in the first place is insulting - implying trickery, false pregnancies, and all sorts of promises that are never kept. Treachery.
