This is a baking book full of rainbows and unicorns. The presentation is nice, with clear photographs and extra unicorn pictures adorning the pages. Recipes are split into four sections: whole cakes, small bakes, biscuits and cookies, and sweets and desserts. Making things rainbowy means food colouring, which the book does discuss. The notes match my experiences. Liquid ones tend to flavour things when enough is used for dark colours, as well as often making mixtures too runny. The book doesn't say it, but liquid red is a big culprit for taste, as it's often beetroot. I used gel colourings, as these are easily available and go bright without making things taste odd. The recipes have clear lists of things needed. Quantities are written out in full, so it says tablespoon rather than abbreviating it. This makes recipes a lot more accessible. There's a wide range of things available, from fudge to bagels. Though the first impressions were good, the next step was to make things and see how the instructions held up. My biggest project was the anti-gravity cake. This is a full-sized cake decorated to look as though rainbow sprinkles are pouring out of a floating jar above it, plus an optional unicorn. I chose this as a birthday cake. It isn't noted in the recipe, but the unicorn used is from a toy range, rather than being sold as a cake topper. It makes it a good choice for children and adults like me, as it means the birthday person gets to keep the toy. I got the exact same unicorn as the book for my attempt at the cake. The only thing I switched out was the sprinkles: I used strands instead of confetti.
