I have a reverse of that; not sure if it supports your statement or refutes it, but it exists nonetheless...
About 15-20 years ago I was sent to a micro-miniature circuit repair course in the Marines. We spent 10 hours a day, for six straight weeks, basically soldering SMT circuit boards nonstop under microscopes. To keep from going totally insane we had a radio on, playing the only station in the area. It played the same handful of songs OVER and OVER. To this day, if I hear one of those songs, I smell the strong odor of burning flux. Not just the memory of it; I really smell it!
No, memories trigger smell and smell triggers memories.
I imagine you can call up a memory of grandma's kitchen and smell cookies (or something), too, if you tried.
The second strongest triggers are songs, BTW.
So you have both going in this example.
