I should admit that i was only just over 2 , when thje war ended, but do remember sweet rationing !!. I think it is correct that the most important thing was that nothing was wasted, whether it be scraps that went to a neighbour's (or in our case relative's) pig, or the fact that you didn't leave anything on your plate. Certainly the records say that no-one starved and people on the whole had enough food. Compared to then, people are wasteful (and , if they really would let the grocer take the communal produce from the garden and sell it back to them, probably stupid). Nothing was wasted then . Anything that might be used to feed people and make life more acceptable was tried. i know from the records that Cadburys , at the beginning of the war had a lot of cocoa butter, which they could not use for chocolate because of lack of sugar, an dfound it made a very good cake. They also found that mangle worzels , cooked to make it slightly less tough, could be immersed in a sugar syrup and ginger flavour to make a passable crystallised ginger - though i think the shortage of sugar prevented this from being carried out. What the program showed was that, people today are so changed in tastes and outlook that thye would have a very big shock if they were dumped into the wartime community
