This book is what it says: definitive, but delightfully so. There is barely an ingredient that does not have its own recipe: multiple, subtly different, versions from the old favourites - vanilla (9), chocolate (17) and strawberry (4) - to the exotic: gin and tonic, lychee and lime or rosewater sorbets; saffron, green tea or avocado ice-creams. No better recipes exist anywhere for the ultimate expresso coffee or brown bread ice-creams (I've had my share of disasters at both until I got this book). Alcohol in ice-cream is well explained, as are all the underlying scientific dimensions to freezing different types of mixture to create a perfectly balanced texture: neither grainy nor watery. There is a thoroughly researched and fascinating history of ice-cream making from the 18th Century, and of selling ice-creams in places as diverse as Glasgow, Paris and Baltimore. All ingredients and recipes are 'translated' for those ice-cream aficionados on both sides of the Atlantic to have no trouble making - whether your taste is for Cornish clotted cream, Scottish rhubarb or English stilton; or dulce de leche, spiced pumpkin or tequila,; whether you buy 'whipped' or 'heavy' cream, and use quarts or litres. More global ices are also well represented: a fail-safe kulfi, an excellent halva and a mai tai sorbet are examples. Over 200 recipes, and each one works a treat. This book is an ice-cream lover's ideal bedtime reading: a host of heavenly recipes to dream of, and then make and enjoy. Everyone with an ice-cream maker should buy this book; but all recipes explain how they can be made without. My most indispensible specialist food cook book, and possibly even the one book I'd take to my Desert Island on the grounds that if you can't have ice-cream you can at least think about it.
