Cooking with your kids is almost certain to improve your own family mealtimes, but the benefits can extend beyond your immediate family, too. Have your children ask an older relative about the traditional foods in your family, and see if kids can get grandparents, aunts or uncles to divulge a closely guarded "family secret" recipe and prepare it (with grandparents' help) for mom and dad.
Give kids the opportunity to cook with their grandparents as often as you can, learning recipes that their grandparents make. Have kids ask their grandparents what their favorite foods were when they were children, then surprise them by helping your children make that meal for a birthday or special occasion. Better still, let kids videotape their grandparents making their specialty. Your kids will love it, your parents will love to share it and you'll be able to preserve it for posterity!
