A maven is most often defined as an expert or connoisseur. We're no experts on cooking. But I think we are all experts on what we like and what we don't like. And that's where our favorite definition comes in...."one who passes on knowledge".
That's what we mean when we say maven. We're passing on the knowledge that, hey, we really like this recipe and want to share it with you. And we sincerely hope you enjoy it!
