All you wanted to know about making cookies but were afraid to ask! The authors even describe the book as "A collection of recipes for cookies of all types, shapes, and sizes, and for every occasion".
The authors cover "What you should know about cookies before you begin", and substitutions. Then they have sections on cookies for home, school, seasonal cookies, cookies to mail, cookies to decorate, party cookies, Christmas cookies, and cookies with a foreign origin. Each section has a sub-section on drop, ball, bar, rolled, pressed cookies as necessary.
