For the past few years my wife and I have been part of something called Moveable Feast (yeah, sorry, I didn't name it). It's just us and 2 other couples, and we get together roughly every other month to cook a collaborative dinner together. The basic concept is that the venue of the meal rotates between the homes of the 3 couples, and the hosting couple gets to set the theme. It's not firmly cookbook-based per se but the hosts could (and have) set a theme that is specifically based on recipes from a single book. More often, though, the themes are based on a region (e.g. Yucatan, Provence) or a specific type of cuisine (Izakaya, stuffed foods, orange foods) .
In any case, it's an extremely enjoyable and educational endeavor. I've learned a lot and have also really pushed the boundaries of my cooking abilities. It's very satisfying to learn how to cook things I've eaten many times, and add them to my knowledge base and cooking repertoire.
Having the event scheduled regularly keeps me from getting complacent, and having 2/3 of the themes set by the other couples is a great way to get me out of my comfort zone, and cooking things that I might not have ever attempted otherwise.
