Once, when we were preparing a meal, our South African friend asked if we had any paper. 'What sort of paper?' we enquired.
'Black paper', she replied.
It seemed an odd request at an odd moment, but she was a creative type. After an exhaustive search, my sister unearthed a sheet of black cartridge paper in an attic and triumphantly presented it.
'No', she said, looking at us as if we were disturbed. 'Black paper. You know - paper and salt. For seasoning.'
