I would put in favorite recipe(s) from each family member and a corresponding picture or two of that person or prepared recipe. I'd list any possible variations for the recipe and share a cute story about the person and/or the recipe when possible. I would also picture family heirlooms that were (and still are) used in the kitchen. If possible, I would have that family member sign their respective recipe(s) , to add yet another ingredient of personalization.
I would add in "wisdom recipes;" those old fashioned bits of information that remind people to always add love in their cooking and that tell of the simple things that make a happy home and such.
My cookbook would include "Old but very useful tips" on how to tell if the yeast is good before adding it to bread dough recipes; how to choose ripe fruits; the butcher's meat diagram; product conversion charts; the many uses of baking soda; cleaning tips with club soda, etc. I would also list websites to helpful online cooking sites so that my book could span through the ages.
My cookbook would even have a "Good to the Last Laugh" section: recipes and/or stories of when food served did not turn out just right and yielded an hilariously unforgetable moment.
I would name my cookbook "Of All The Places I've Ever Served My Guests, It Seems They Like My Kitchen Best!"
I would name my cookibook this because of a plate that hung in my late grandmother's kitchen wall; I would picture it as the cover of my cookbook as well. When I was a small girl, I asked her about it and she told me that it is true. Everytime she was hostess to a party at her home, the guests would all marvel at her attention to detail in all of the decorations, rave over her food preparations and thoroughly enjoy the time spent together for the evening, and inevitably they would always end up in her kitchen! I then understood it all - you could really feel the love in my grandparents' home from the moment you opened the front door, especially in my grandmother's kitchen! I now have that plate in my own kitchen that reminds me of her and those very special times together!
