I know tinned pineapple isn’t very popular these days, but back in the 70s it seemed to appear in lots of sweet and savoury dishes.  In going through Mum’s collection I’ve discarded many of them as I just don’t think anyone would want to make them now.  This one seemed to be a bit of an exception mainly, I think, as the berries add a tartness into the mix and that would counteract some of the sweetness of the pineapple, which in my opinion is the main problem with with tinned pineapple. (The biro underlining is Mum’s so she must have thought it would taste OK.)
