I'm loving the Preschool Cookbook we got James for Yule. The book is Pretend Soup, by Mollie Katzen. It's got pictures with each recipe so even my three year old can see what to do next. The recipes are just right for preschoolers too- not too complex, and tasty. James gets very into selecting what he'd like to make and we put the ingredients on the grocery list. You can see the book in the recipe stand below.
Chocolate Banana Shake:
1 Cup Milk
3 Ice Cubes
Put all ingredients in Blender. Blend. Pour. Drink.
Yes it sounds simple, but the magic is that James is getting to flip through the book, decide from the pictures what he'd like and see how to make that very thing, and then find that he actually is able to do it.
