“Do you know your Brussels Sprouts from your Brassicas?” reads the description of this app, created by the renowned West London cookery school. The randomised 10 question quiz may embarrass you if the answer to the aforementioned question is “who are the Brassicas?”, but it will also help you learn the answers. The app is fairly basic, but great fun and worryingly addictive. The makers have created a good balance of questions that are genuinely perplexing and those which are somewhat simpler, meaning (hopefully) no one’s left feeling fed up or foolish but everyone’s going to get a moment of enlightenment. You want to know the best bit? It’s free.
