Does anybody know of a book or paper that tracks the ancestry of
copied recipes in the 18th century?

In her great book "The British Housewife" Gilly Lehmann points out
that Elizabeth Moxon's 1741 "English Housewifry" was plagiarised
virtually holus bolus by Sarah Jackson in her 1754 "The Director".

It is not the mere fact that plagiarism has been recognised that
interests me. What I am looking for is the tracked ancestry, together
with the various texts, of recipes that might have titles such as 'to
stew Hare', 'to make Ratifie Drops', 'forc'd Mutton leg' and 'to
pickle Onions'.
