I’m not sure many people associate McVitee's Jamaica Ginger Cake with calculus but I am one of them.
I never knew it existed until I was studying A Level Further Maths. There were several maths classes in my year at college but only a handful of us were nuts enough to do a second A level on the subject. By the time we reached the upper sixth an even smaller number of us remained. We were blessed with a cheerful Geordie teacher who was happy to interrupt our two-hour lessons for a sneaky tea break. If we put 20p in the ‘charity pot’ we were entitled to a cuppa and the chance to help ourselves from the biscuit tin. By the end of the year we had accumulated £76 for Guidedogs for the Blind.
Anyhoo, sometimes the biscuit tin wasn’t called for because there was cake. Specifically, Jamaica Ginger Cake (I never recall any other type of cake being on offer). Definitely a bonus day.
I can’t say it’s the most gingery thing on the planet. In fact, were it not for the label, one might have difficulty identifying the flavour, beyond something vaguely warm and spicy. I mean, we’re not even talking about the still-fairly-tame-but-at-least noticeable levels of ginger in gingernut biscuits. But no matter. It is sticky, claggy, warming and friendly. And makes 3D vectors marginally easier to deal with. Happy days.
