Leon: Baking & Puddings is their third cookbook, and contains hundreds of recipes for everyone from the novice cook to the baking aficionado. Following the Leon principle that what tastes good can also do you good, three-quarters of the recipes are sugar, dairy, wheat or gluten free - so there's plenty to indulge in even if you have a food allergy, an intolerance or one eye on your waistline. Co-authored by Henry Dimbleby and Claire Ptak, it is a book of two halves. The first contains recipes for Every Day: granolas, cakes, breads, pizzas, and puddings to enjoy as often as you like. The second half - Celebration - contains recipes for all sorts of special occasions, from Easter and Christmas to weddings and even funerals.
