Re: As a child of the 1970s, I have a fear of savoury dishes involving fruit...
" Only marginally less disgusting than 60s school tapioca, [...]"
Our school dining hall was arranged with eight pupils to a table. Food arrived in large mess tins - and was then divided evenly into eight portions. Rarely did the tins return other than empty*** - as there were always the dynamics like Jack Sprat and his wife. Tapioca with a dollop of jam - yummy!
***on one occasion most tables returned their meatballs untouched. The previous serving of that dish many months earlier had incapacitated most of the school with food poisoning the next day. IIRC meatballs were never served again in the rest of my years there.
