Psychologist explores the impact of sniffing a fairy cake.

However, since attending my friends’ fabulous royal wedding party on Friday night I feel I need to make an important amendment to my earlier statement: I now realize that the most important thing about the whole business was the opportunity to indulge in a glorious nationwide orgy of Party Food Nostalgia. We all have foods that take us back to happy times and places. Personally, if I so much as sniff a party ring, a fairy cake, or a cheesy wotsit, I am immediately at my 7th birthday party, sitting cross-legged on our dining room floor, watching wide-eyed as my dad’s magician friend Graham crafted giraffes and sausage dogs from colored balloons, and made 50 pence pieces vanish in thin air, then mysteriously re-emerge.
