It's hard to lock down the source of this memory, but I'm going to take a stab in the dark and guess that it comes from the many trips our family took in the early eighties to places like Taupo and Stratford. As you might expect, a trip to a fish 'n chip shop was mandatory along the way, and I distinctly remember that you could buy chocolate donuts. Now, of course, you can still buy chocolate donuts, but nothing like these. These were put into the deep fryer right in front of you, cooked until golden brown, and then dipped into a large vat of chocolate sauce until coated to a glorious and obscene thickness.
It's a reflection of my advancing decreptitude that whilst I would like to say "I could kill for one of those right now", I am instead reduced to "I could die from one of those right now".
