Simon Difford's latest book is a departure from his previous works, as well as from the current cocktail book trend generally. Instead of the 2500+ recipes in his Difford's Guide books or the sometimes complicated seasonal drinks requiring exotic ingredients, Difford's new book Cocktails Made Easy includes 500 drinks that can be made with only 14 ingredients. That'll save some space in your bar.
I assume those 14 ingredients are all spirits and don't include the juices and sodas as mixers, but still I think this is a great idea. More information here.
