If we're going to be pedantic about language use (and it appears that we are): "cf" is short for the Latin for "compare [with]". To me, that only makes sense when the reference is something very analogous, e.g. you're talking about caramelising onions and you cite an article about caramelising carrots. Most of the time it's used, including this time, it would be more appropriate to just say "see also".
