Nostalgia is roughly defined as a yearning or wistful attachment to the past. Sort of like classic rock buffs who think that there hasn’t been a single good song written since 1977, so they keep spamming the same record for the past 40 years. Nostalgia usually coincides with the feeling that the past was somewhat rosier and better than the present.Which food reminds you most of your childhood? Is it school dinner classics like macaroni cheese, or sponge and custard? Or home cooking like a roast dinner on a Sunday? Perhaps it’s even a paper bag of sherbet or cola cubes from the sweet shop, or a summer special like a choc ice or Mr Whippy cone.
