You have done your dad proud! I am teaching my son(13) how to cook and some of my recipes, that is some cool father son time..
One thing my wife's mom did that I thought was cool, is she made a family recipe cook book and gave it to her daughters one year for Christmas. There are generations of recipes in there.
That's an awesome idea! My oldest is only 6 right now, but I do plan to teach him in a few years. I get him to help me with carrying utensils now though.
