I have one you can have for £2.50 inc p&p. It is called Step By Step Easy Cooking for boys & girls. Recipes (photos & drawings) include:
Hot Pots of Goodness
Meals on a stick
Scones & shortbread
Cakes to bake
Plus "Did you know sections" such as did you know how to tell if an egg id fresh? A fresh egg will sink in water, an old egg will float!

Would be happy to give you a list of what's in the book if you cat me although have just looked on Amazon and you can actually look in the book via the website... Here is the link: here
