Older people exposed to food flavors from their youth were able to 'time travel' back to the past with an enhanced memory of the event. For food memory, the researchers worked with the participants to create bespoke flavor-based cues for each one. The 3D printed flavour-based cues are small edible balls, modelling the original food. A striking outcome was the large number of memories cued by flavours recalled with strong feelings of being brought back in time.
