Calling all big kids: there’s a new range of Roald Dahl cocktails for you to sample.

The literary tipples are "the perfect blend of childhood nostalgia and adult naughtiness," says their creator Matt Spencer, who has designed the unusual recipes in time for the legendary author's 100th birthday next week.

Spencer has concocted the drinks exclusively for Barnstaple’s Bull & Bear and is sharing his recipe for Wonka's Choco’mallow Martini with Stylist.co.uk.

Roald Dahl cocktails are here and they're far from revolting
