Internal linking is never a bad thing. But understand that your breadcrumbs already provide a link from “every recipe to their appropriate category.” You link in the post, naturally, when it makes sense to the users. So sure, if you have a “banana cream pie recipe” and you want to encourage users to check out your other pies, then say “hey, if you loved this pie you’ll love my other pies in the pie category here,” as an example.
