When asked about a job that changed his life by Harper's Bazaar during a January 2021 interview, Jonathan said that it was working on the lemon-curd line at a local factory as a kid. It was a tough job, and according to Jonathan, it made him realise the value of hard work — and how much he hated doing manual labour. "Every summer, Christmas, holidays, at school, there's something about having to open up a piping hot vat of lemon curd to check the temperature at five in the morning . . . It made me realise that I don't ever want to eat or have lemon curd ever again," he joked.
