I think we all have more cookery books than we will ever get through. Browsing ours, I guess we only ever cook one or two recipes from each book. Some of these become 'regulars' but many are one offs.
I have one Indian cook book which I have cooked lots of recipes from and written the date and rating (stars 1 to 5) against. But generally ours are never that well used. One of our latest books, Bosh!, I think we have cooked just two things from, both of which actually where excellent.
So, Wendy and I are going to branch out a bit. We have decided each week to cook two completely new recipes. I will cook Indian (I think there must be thousands of Indian recipes) and Wendy will have free reign to cook any other style.
As they say variety is the spice of life!
