I would have to paraphrase the narrative (ie the instructions,/directions, not the list of ingredients), correct?
Correct!
If I change the measurements, is it technically my own, but “inspired by” the original author? When would I use the phrase, “adapted by”?
There is no legal requirement to use the phrase “inspired by” or “adapted by”. It’s totally up to you. The list of ingredients can’t be copyrighted, so just by using the ingredients, you’re not really “adapting” anything. You’re just cooking and writing about what you cook.
Now I personally think it’s nice to give a shout out to what inspires you – if you find a particular recipe on a particular blog, then go ahead and link back to it and say that you adapted this person’s recipe. Or that you were inspired by it.
Ok, as an example, I’m about to blog about making pate. I searched 5 or 6 different recipes and combined them to come up with my recipe. But pate is pretty generic – liver, some kind of oil, cognac, onion or shallot, etc. So I’m not going to reference or link to any one recipe. I’m just going to write up what I did. Period. I wasn’t inspired by anyone, I didn’t use any particular recipe, I just made pate. Most of hte recipes on my site fall into this category – Chimichurri sauce, same thing. I wanted to make it, looked up a half-dozen different recipes, then made it from a compilation of various recipes. No credit or attribution to anyone.
On the other hand, here’s a recipe that I used from Gordon Ramsay’s “The F Word” and I gave credit where credit was due and then said I adapted the recipe slightly:

Here’s one from the Dorie Greenspan book that I made EXACTLY by her recipe – notice that I didn’t publish her recipe, which is hers, but instead I linked to her book and said that the recipe can be found there:

Here’s one for you where I realized after I made it that I was totally unconsciously influenced by Ree (Pioneer Woman) so I linked back to her site and gave her an attribute:

IMO, once you get outside the legalities of it, it’s all about treating people the way you’d want to be treated. I don’t expect anyone to give me a link if they see lasagna on my site and decide to go make lasagna from an old family recipe or even to make one from Joy of Cooking or whatever. If they make the exact same lasagna that I made, then it would be nice for them to say “hey I saw this on Kara Cook’s site and it really made me want to make one of my own” … but even so, I wouldn’t be upset if they didn’t. The only thing that would upset me is if they copied my recipe word for word or used my images .. then we’d have an issue.
