My wife has a blog where she posts all her old and new recipes for the kids to enjoy. She posts her new ones so that they can see what we are eating! They live 450 miles away, so they don't come over for supper very much.
For Christmas I bought blank cookbooks for all five of our kids. I told them to give them back to me and start telling me their favorite recipes and I will begin to fill them for them. They thought it was great!
I bought a cookbook binder for each of my kids last Christmas. I typed up all my old usual recipes and put them in it. I told them I didn’t want them to, some day, years in the future, wonder how I made some old recipe.
I included the ones my mom made that don’t really have recipes, their dad’s favorites, and the ones I know are their favorites. They really liked it!
Now, when I find a new recipe I really like, I email it to them, and they can print it out and add it to the binder. Easy.
