I like Threptin biscuits (the regular flavour). I always have since I was about 3 years old. My earliest memory of them is from Agra (of the Taj Mahal fame yes) where we stayed for 2 years from 1980 to '82. The box hasn't changed at all I think. And I like it that they call them diskettes.
A tin lies right within reach as I write this. An unlikely reminder of the past. Mum said her grandfather liked it too... the past just got older!
