Tinned orange concentrate from the freezer section, indeed Sainburys were still selling it in the mid 80's when I worked for them
Mum is the worse cook in the world but she did make a mean Duck A L Orange using it.
I can remember the milkman delivering Orange Juice on a Saturday only, pint bottle just like the milk, you had to pre order it. If it was bought in our house, it wasnt for us kids, we got squash
We have a golf club near us and they do the most amazing carvery on Sundays, its not in the least bit posh, its just good food cooked well, its the best Sunday dinner ( other then mine obviously ) but the starters and desserts are straight out of the seventies. Prawns with manderin in a marie rose sauce anyone? Or Melon with a fruit "jus' and cream? and the breaded deep fried mushrooms :) Desserts are seriously tinned fruit and ice cream and trifle as it was made at home and blancmonge :)
Back to the orange juice, lidl here have introduced the self serve fresh squeeze orange juice machines. I remeber them coming into stores in the 80's and there being queues to the doors for it
