We have lots of cookbooks for kids, and looking through them will reward you with a number of interesting things that could be made for presents. No-Cook Cooking by Ting and Neil Morris has recipes for creations that don't even require use of the stove. On pages 6 and 7 I found directions for muesli, which is to be stored in a big jar with a lid. This would be a simple thing to stir up -- all you'd need to do would be to gather oats, sunflower seeds, raisins, and other similar stuff -- okay, that could take a while. But after that mixing it would be simple.
Children's Step By Step Cook Book, published by Dorling Kindersley, of course includes lots of photographs like all of Dorling Kindersley publications, and they really are step by step. The Gingerbread Folk which begin on page 78 have quite complete directions, with each step illustrated. Icing directions follow. Yum!
Emeril's There's a Chef in my Soup! Recipes for the Kid in Everyone includes a recipe for Baby Bam on page 234. It can be stored in an airtight container for 3 months. And of course he tells you how to kick it up a notch!These cookbooks are for children, but the eaters could be of all ages!
