I've bought a lot of baking books and after buying this one I wish I hadn't bothered with any others. It is by far and away the most reliable and useful cake book I have ever used - in particular I found it a much better buy than Leith's enormous Baking Bible. There are sections on chocolate cakes, meringues, traybakes, celebration cakes, cheesecakes, scones and teabreads, biscuits and shortbread, continental cakes, family cakes, little cakes, cakes for bazaars and fetes, cakes for children to make, cakes and biscuits for presents, and healthy cakes and biscuits. There are also very useful sections on ingredients, equipment and methods, and a section on questions and answers. (These sound dull, but in fact they teach you a lot about cake-making.)
Every cake I have made from it has worked and has been delicious and has evoked the sort of compliments I have (sadly) never received before for my cakes.
One of the best things about it is that there is such a range of cakes in terms of difficulty and time. There's plenty to make if you've only got an hour before the children get home from school. There's also plenty to make if you've got a whole morning to potter and create something complex.
I'm thinking of getting rid of my other cake books. This really is the only one you'll ever need.
