Where to watch: Amazon, (Banana and Tofu on All4).
What it's about: A super fun, sometimes racy, and sometimes darkly poignant series about a gay man living in Manchester and struggling with his identity. This series is wonderfully written, incredibly well portrayed, and diverse in its storytelling. It also has two spin-off series – Banana (a web series focussing on some of the younger cast of Cucumber) and Tofu (an IRL sex education series).
