We inherited some stuff from my uncle (like 40 years ago). He had sugar stored in glass containers and bars of soap all over the place. The soap was pre-WWII labeled (that would made it than like 50 years old). The sugar was from that time probably too. Both were OK.
Just to be safe, we used the sugar boiled. Took us quite a while to consume it all, good as new.
That’s amazing. We had some old spices, of my grandmothers, in old tins.....still looked and smelled great.
I would love to see those WWII era soap bars! Talk about a walk back in time.
