Well, I may not be able to do any more until Monday as we are ways this weekend in Malvern with friends. I was born in 1955, so many of these things were still true in the early 60s. I love all the additions you are coming up with.
Herbs were used to make rather dodgy medicine
Bananas and oranges were only seen at Christmas
A chinese chippy was a foreign carpenter
Oil was for lubricatiing your bike, not for cooking. Fat was for cooking
Tea had only one colour - black. Green tea was not British
Coffee was only drunk when we had no tea, and then it was called Camp and came in a bottle
Healthy food consisted of anything edible
A seven course meal had to last a week.
If we had eaten bacon, lettuce and tomato in the same sandwich, we would have been certified
Cooking outside was called camping
