Smoothies & Juices: The Essential Recipe Handbook contains over 250 healthy recipies, with each one providing great pictures and simple instructions. Written by the respected Gina Steer and published by Star Fire, the book looks at a number of recipies that you can make using a juicer, a smoothie maker and/or a blender.
Some of my favourite recipies from the book include Pear and Raspberry Juice, and Cucummber, Apple & Mint Juice. Be warned, quite a few of the recipies aren't for juicers, but for smoothie makers and blenders. A good book though with some very nice ideas for fabulous drinks. Also, a great touch is that each recipe comes with footnote with a suggested change you can make to create an alternative drink. The rrp is £9.99 but you should see it cheaper if you shop around.
