Decide on one format and the best way is probably to put it all in a scrapbook since the old generation does not exactly know how to use a computer. If you do it that way then you will be able to pave the way for your grandparents to contribute their best recipes to the cookbook. The old people are without a doubt the best cooks because of their years of experience. If you decide to bound a book then it will be very costly but it will be worth it in the end if it is the best collection of recipes you have ever witnessed.
It would be a great idea to surprise family members with the amazing collection of recipes as they will certainly appreciate the fact that you made extra effort to treasure all those recipes. It will show that you are a family person and you care about family members you don’t see often. You must do it at the right time though and not at times when everyone is busy. When you mean sharing it to everyone, you must mean it so the next site generations will know about it too.
