And you know what? I was right.
Maybe it's because our family doesn't keep a cookie jar regularly supplied, as was the norm in the 1940s. Or maybe we ate fewer sweets. Either way, we adapted quite well to the the sugar restrictions. Cookie craving? Better get the recipe book out because you're not getting any unless you put in the effort. And there were several nights when I would have loved a warm, gooey cookie straight from the oven but was too lazy to actually do the work. And that's probably a good thing.
Granted, I did buy the girls Twinkies at one point, since they are a treat that is historically accurate (well, at least in form - I'm not sure if all the same preservatives and artificial colors were used in the past). The girls loved them.
Otherwise, I could go several weeks without claiming our sugar rations and still have plenty available on the shelf. The only time I had to be careful and make sure we had a copious supply was during the summer canning season.
One thing we did fail at was the interest in buying mostly sustainably-grown sugar. That will be something to consider while we make plans for life after rationing.
