We all know the feeling. What starts as an insignificant little niggle, gently hinting at a kind of food, grows into a demanding craving. The kind that drags you out of bed in the middle of the night on a search for cheese, or causes you to break away from your desk in a desperate hunt for chocolate.

Crave is the second book from Sunday Times bestselling author and Great British Bake Off contestant, Martha Collison. Using brilliant food science and delicious flavour combinations, she provides go-to recipes incorporating 8 of those things we so often hanker for: citrus, fruit, nut, spice, chocolate, caramel, cheese - and alcohol! There are 'Instant' recipes such as Lemon Cheesecake Pots - your super quick treats to be rustled up in next to no time. There are 'Soon' recipes that are ready to snaffle in under an hour, like Chilli Chocolate Churros. And you'll find 'Worth the Wait' recipes, too. Think Olive & Preserved Lemon Focaccia and Caramelised White Chocolate Cake - a collection of bakes where patience yields intense flavours and sumptuous textures.

Creative, inspiring and imaginative, these are the recipes you just have to have.

Martha Collison is the youngest ever baker on The Great British Bake Off - she made it all the way to the quarter finals whilst studying for her AS Levels! Martha is a self-taught baker who started cooking at the age of eight - the result of her brave parents letting her loose in the kitchen and enjoying the (sometimes mixed) results. Since then her baking repertoire has grown no end, and she now writes a weekly column in Waitrose Weekend as well as her own blog. Her first book Twist is a Sunday Times bestseller. She loves spending time with her family, and is passionate about helping with charitable campaigns with Tearfund.
