Well at least on a small scale like when school kids makeup a new word and assume it is means something cool and start using it. Do you think many slang words started that way? Hmmโฆ
Anyhow, I wouldnโt have thought Iโd be able to start one with brown sugar. I usually keep my stash of baking ingredients in the cupboard ๐ to avoid someone digging in them (my brother has found my dark chocolate and is using him in his hot chocolate! After my outburst he went and brought me some very nice bars :D) but my sister was annoyed by the clutter (none that I saw) and told me to put the brown sugar in one of the empty jars on the kitchen counter beside the flour and white sugar and then it started.
I donโt take sugar with tea or any hot drink except coffee and hot chocolate they are too bitter otherwise. I have tasted coffee with light brown sugar and I liked it so I started using it in the morning. Once one of my family members saw me using it and one thing led to the next I noticed the jar was emptying rather quickly (odd I thought where did it all go?). I found out when I saw one of them using it and now it is their favorite thing to use thatโs why am always out of light brown sugar. Yet, my dark brown sugar is safe in the cupboard until today when I was using it to make a caramel bread pudding and I wanted to put it away when I saw little dried rose buds in it (what the heck is that?!) then I noticed my mother is cleaning some herbs and spices that she puts in food. I know dark brown sugar doesnโt look yummy but โmom this is not trashโ :S and the answer was โoh I thought it wasโ
